Jog Frequency – The jog speed setting is used whenever the Jog command is active.

The jog speed setting range is arbitrarily limited to 10 Hz, to provide safety during

manual operation. The acceleration to the jog frequency is instantaneous, but you can

choose from three modes for the best method for stopping the jog operation.

Torque Control Algorithms

The inverter generates the motor output

according to the V/f algorithm selected.

Parameter A044 selects the inverter algorithm

for generating the frequency output, as shown in

the diagram to the right (A244 for 2nd motor).

The factory default is 00 (constant torque).

Review the following description to help you

choose the best torque control algorithm for your

application.

The built-in V/f curves are oriented toward developing constant torque or

variable torque characteristics (see graphs below). You can select either

constant torque or reduced torque V/f control.

Constant and Variable (Reduced) Torque – The

graph at right shows the constant torque

characteristic from 0Hz to the base frequency

A003. The voltage remains constant for output

frequencies higher than the base frequency.

The graph above (right) shows the variable (reduced) torque curve, which has a

constant torque characteristic from 0Hz to 10% of the base frequency. This helps to

achieve higher torque at low speed with reduced torque curve at higher speeds.

Sensorless Vector Control – You can achieve high torque performance (200% torque at

0.5Hz of output frequency) without motor speed feedback (encoder feedback), which is

so-called sensorless vector control (SLV control).

Free V/F Control – The free V/F setting function allows you to set an arbitrary V/F

characteristics by specifying the voltages and frequencies (b100~b113) for the seven

points on the V/F characteristic curve.

The free V/F frequencies 1 to 7 set by this function must always be in the collating

sequence of “1<2<3<4<5<6<7”.

Since all the free V/F frequencies are set to 0Hz as default (factory setting), specify their

arbitrary values (being set with free-setting V/F frequency 7). The inverter does not

operate the free V/F characteristics with the factory setting.

Manual Torque Boost – The Constant

and Variable Torque algorithms

feature an adjustable

torque boost

curve. When the motor load has a lot of

inertia or starting friction, you may

need to increase the low frequency

starting torque characteristics by

boosting the voltage above the normal

V/f ratio (shown at right). The function

attempts to compensate for voltage

drop in the motor primary winding in

the low speed range.

The boost is applied from zero to the base frequency. You set the breakpoint of the boost

(point A on the graph) by using parameters A042 and A043. The manual boost is

calculated as an addition to the standard V/f curve.

Be aware that running the motor at a low speed for a long time can cause motor

overheating. This is particularly true when manual torque boost is ON, or if the motor

relies on a built-in fan for cooling.

Voltage gain – Using parameter A045 you can

modify the voltage gain of the inverter (see

graph at right). This is specified as a

percentage of the full scale output voltage.

The gain can be set from 20% to 100%. It

should be adjusted in accordance with the

motor specifications. Gain can be changed

even during operation in V/f mode, and while

stopped in SLV mode. When the setting is

changed , reset (RS terminal on/off) is to be

executed so that the motor constants are

re-calculated.

After the setting is done, please be sure to reset (terminal RS on/off) to recalculate

the motor constant.

Refrain from change the setting value suddenly (within 10%). Inverter may

overvoltage trip due to the rapid change of output voltage.

Voltage compensation gain and slip compensation gain – Using parameters A046 and

A047, you can obtain better performance under automatic torque boost mode (A041=01).

See following table for the concept of adjustment, including other parameters.

DC Braking (DB) Settings

Normal DC braking performance⎯ The DC

braking feature can provide additional

stopping torque when compared to a normal

deceleration to a stop. DC braking is

particularly useful at low speeds when

normal deceleration torque is minimal.

When you set A051 to 01 (Enable during stop), and the RUN command (FW/RV signal)

turns OFF, the inverter injects a DC voltage into the motor windings during

deceleration below a frequency you can specify (A052).

The braking power (A054) and duration (A055) can both be set. You can optionally specify

a wait time before DC braking (A053), during which the motor will free run.

DC Braking – Frequency Detection ⎯ You can instead set DC braking to operate during

RUN mode only, by setting A051 to 02 (Frequency detection). In this case DC braking

operates when the output frequency comes down to the one you specified in A052 while

the RUN command is still active. Refer to the graphs figures below.

External DB and Internal DC braking are invalid during the frequency detection mode.

Example 1, (above left) shows the performance with A051=02 with a step-changing

frequency reference. In this case, when the reference goes to 0, the inverter immediately

starts DC braking because the set point drops below the value specified in A052. DC

braking continues until the set point exceeds A052. There will be no DC braking at next

downward transition because the FW input is OFF.

Example 2, (above right) shows a gradually changing frequency reference, for example

by analog input. In this case, there will be a DC braking period at starting because the

frequency set point is lower than the value specified in A052.

CAUTION: Be careful to avoid specifying a braking time that is long enough to cause

motor overheating. If you use DC braking, we recommend using a motor with a built-in

thermistor, and wiring it to the inverter’s thermistor input (see “Thermistor Thermal

Protection” in chapter 4). Also refer to the motor manufacturer’s specifications for

duty-cycle recommendations during DC braking.

DC braking performance at start can also be set separately (a057 and a058).

And carrier frequency of DC braking performance can also be set separately (a059).

CAUTION: Be careful to avoid specifying a braking carrier frequency that is high

enough to cause inverter and motor overheating. If you use DC braking, we recommend

using a motor with a built-in thermistor, and wiring it to the inverter’s thermistor input

(see “Thermistor Thermal Protection” in chapter 4). Also refer to the motor

manufacturer’s specifications for duty-cycle recommendations during DC braking.

In standard operation, the inverter uses a reference source selected by parameter A001

for the output frequency, which may be a fixed value (F001), a variable set by the front

panel potentiometer, or value from an analog input (voltage or current). To enable PID

operation, set A071=01. This causes the inverter to calculate

the target freq, or setpoint.

A calculated target frequency can have a lot of advantages. It lets the inverter adjust

the motor speed to optimize some other process of interest, potentially saving energy as

well. Refer to the figure below. The motor acts upon the external process. To control that

external process, the inverter must monitor the process variable. This requires wiring a

sensor to either the analog input terminal [O] (voltage) or terminal [OI] (current).

When enabled, the PID loop calculates the ideal output frequency to minimize the loop

error. This means we no longer command the inverter to run at a particular frequency,

but we specify the ideal value for the process variable. That ideal value is called the

setpoint, and is specified in the units of the external process variable. For a pump

application it may be gallons/minute, or it could be air velocity or temperature for an

HVAC unit. Parameter A075 is a scale factor that relates the external process variable

units to motor frequency. The figure below is a more detailed diagram of the function.

PID Loop Configuration

The inverter’s PID loop algorithm is configurable for various applications.

PID Output Limit - The PID loop controller has a built-in output limit function. This

function monitors the difference between the PID setpoint and the loop output (inverter

output frequency), measured as a percentage of the full scale range of each. The limit is

specified by parameter A078.

• When the difference |(Setpoint – loop output)| is smaller than or equal to the A078

limit value, the loop controller operates in its normal linear range.

• When the difference |(Setpoint – loop output)| is larger than the A078 limit value,

the loop controller changes the output frequency as needed so that the difference

does not exceed the limit.

The diagram below shows PID setpoint changes and the related output frequency

behavior when a limit value in A078 exists.

Deviation (error) Inversion - In typical heating loops or ventilation loops, an increase in

energy into the process results in an

increasing

PV. In this case, the Loop Error = (SP –

PV). For cooling loops, an increase in energy into the process results in a

decreasing

PV.

In this case, the Loop Error = –(SP – PV). Use A077 to configure the error term.

PID Sleep Function

The inverter shuts off the output when the PID output becomes less than the specified

value (A156) in case of PID is set enabled, or shuts off when the frequency command

becomes less than the specified value in case of PID is set disabled. And if the PID

output or frequency command exceeds the specified value (A156) for a specified period

(A157), inverter automatically restarts the operation. This is the PID sleep function.

 PID Sleep function is always enabled, even the PID function is disabled.

Automatic Voltage Regulation (AVR) Function

The automatic voltage regulation (AVR) feature keeps the inverter output waveform at

a relatively constant amplitude during power input fluctuations. This can be useful if

the installation is subject to input voltage fluctuations. However, the inverter cannot

boost its motor output to a voltage higher than the power input voltage. If you enable

this feature, be sure to select the proper voltage class setting for your motor.

Note: The motor behave as generator during deceleration and the energy is regenerated to

trip when exceeding the OV level. When the voltage is set high, deceleration time can

be set shorter thanks to the energy consumption due to the incensement of loss in

inverter. In order to set deceleration time shorter without over-voltage trip, please try

to set AVR off during deceleration or to tune the AR filter time constant and AVR

deceleration gain.

Energy Savings Mode / Optional Accel/Decel

Energy Saving Mode – This function allows the inverter to deliver the minimum power

necessary to maintain speed at any given frequency. This works best when driving

variable torque characteristic loads such as fans and pumps. Parameter A085=01

enables this function and A086 controls the degrees of its effect. A setting of 0.0 yields

slow response but high accuracy, while a setting of 100 will yield a fast response with

lower accuracy.

Overload Restriction Function if enabled (Parameters b021, b022, and b023). If Overload

Restriction is not enabled, then the current limit used is 150% of the inverter’s rated

output current.

The deceleration time is controlled so that the output current is maintained below 150%

of the inverter’s rated current, and the DC bus voltage is maintained below the OV Trip

level (400V or 800V).

NOTE: If the load exceeds the rating of the inverter, the acceleration time may be increased.

NOTE: If using a motor with a capacity that is one size smaller than the inverter rating,

enable the Overload Restriction function (b021) and set the Overload Restriction Level

(

b022) to 1.5 times the motor nameplate current.

NOTE: Be aware that the acceleration and deceleration times will vary, depending on the

actual load conditions during each individual operation of the inverter.

NOTE: When analog input is a source of frequency command, be sure to set analog filter

“B” Group: Fine Tuning Functions

The “B” Group of functions and parameters adjust some of the more subtle but useful

aspects of motor control and system configuration.

Automatic Restart Mode

The restart mode determines how the inverter will resume operation after a fault

causes a trip event. The five options provide advantages for your applications.

Frequency matching allows the inverter to read the motor speed by virtue of its residual

magnetic flux and restart the output at the corresponding frequency. The inverter can

attempt a restart a certain number of times depending on the particular trip event:

• Over-current trip, restart up to 3 times

• Over-voltage trip, restart up to 3 times

When the inverter reaches the maximum number of restarts (3), you must power cycle

the inverter to reset its operation.

Other parameters specify the allowable under-voltage level and the delay time before

restarting. The proper settings depend on the typical fault conditions for your

application, the necessity of restarting the process in unattended situations, and

whether restarting is always say.

If the actual power failure time is

shorter than the B002 set value,

inverter resumes from the set

frequency in B011.

The resumption mode is called

“active frequency matching” and

the inverter performs reduced

voltage start to avoid over-current

trip.

If the motor current exceeds the

B030 set value during this period,

the inverter decelerates according

to the B029 set value and helps to

reduce the motor current.

When the motor current is less

than B030, the inverter increases

motor speed toward the set speed.

The inverter continues this retry

process until the motor speed

comes to the previous set speed.

Overload restriction (B021~B028) is not valid when active frequency matching is

activated.

If the actual power failure time is longer than the B002 set value, the inverter does not

resume and the motor will coast to stop.

Electronic Thermal Overload Alarm Setting

The thermal overload detection protects the inverter and motor from overheating due to

an excessive load. It uses a current/inverse time curve to determine the trip point.

First, use B013 to select the torque characteristic that matches your load. This allows

the inverter to utilize the best thermal overload characteristic for your application.

The torque developed in a motor is directly proportional to the current in the windings,

which is also related to the heat generated (and temperature, over time).

Therefore, you must set the thermal overload threshold in terms of current (amperes)

for parameter B012. The range is 20% to 100% of the rated current for each inverter

model. If the current exceeds the level you specify, the inverter will trip and log an event

(error E 05) in the history table. The inverter turns the motor output OFF when tripped.

Separate settings are available for the second motor (if applicable) as shown in the

following table.

against motor overheat. You can also set the threshold level to output a warning signal

with the electronic thermal warning level setting in function “C061”.

To output the warning signal, assign parameter “13” (THM) to one of the intelligent

output terminals [11] to [12] (C021 to C022), or to the relay output terminal (C026).

Overload Restriction: B022 If the inverter’s

output current exceeds a preset current level

you specify during acceleration or constant

speed, the overload restriction feature

automatically reduces the output frequency

during powering drive (and can increase the

speed during regeneration) to restrict the

overload. This feature does not generate an

alarm or trip event. You can instruct the

inverter to apply overload restriction only

during constant speed, thus allowing higher

currents for acceleration. Or, you may use the

same threshold for both acceleration and

constant speed.

You can specify two types of overload restriction operation by setting functional items

B021, B022, B023, and B024, B025, B026 separately. To switch between these two is done

by assigning “39 (OLR)” to an intelligent input terminal and make it ON/OFF.

When the inverter detects an overload, it must decelerate the motor to reduce the

current until it is less than the threshold. You can choose the rate of deceleration that

the inverter uses to lower the output current.

Over-current Trip Suppression: B027 – The

Over-current Trip Suppression function

monitors the motor current and actively

changes the output frequency profile to

maintain the motor current within the limits.

Although “LAD” refers to “linear acceleration /

deceleration”, the inverter only “STOPs” the

acceleration and deceleration ramp so that it

will not cause an over-current trip event.

The graph at right shows an inverter output

profile that starts acceleration to a constant

speed. At two different points during the

acceleration, motor current increases and

exceeds the fixed level of Over-current Trip

Suppression level.

When the Over-current Trip Suppression feature is enabled by B027 = 01, the inverter

stops the acceleration ramp in each case until the motor current level is again less than

the threshold value, which is approximately 180% of the rated current of the inverter.

When using the Over-current Trip Suppression feature, please note the following:

• When the feature is enabled (B027 = 01), the actual acceleration may be longer

than the value set by parameters F002/F202 in some cases.

• The Over-current Trip Suppression feature does not operate by maintaining a

constant motor current. So it is still possible to have an over-current trip event

during extreme acceleration.

Software Lock Mode

The software lock function keeps personnel from accidentally changing parameters in

the inverter memory. Use B031 to select from various protection levels.

The table below lists all combinations of B031 option codes and the

ON/OFF state of the [SFT] input. Each Check

 or Ex U indicates

whether the corresponding parameter(s) can be edited. The

Standard Parameters column below shows access in permitted for

some lock modes. These refer to the parameter tables throughout

this chapter, each of which includes a column titled

as shown to the right.

The marks (Check

 or Ex U) under the “Run Mode Edit” column title indicate

whether access applies to each parameter as defined in the table below. In some lock

modes, you can edit only F001 and the Multi-speed parameter group that includes A020,

A220, A021–A035, and A038 (Jog). However, it does not include A019, Multi-speed

Motor Cable Length Parameter

To achieve higher motor control performance, the WJ200 inverter has the Motor Cable

Length Parameter setting B033. Normally there is no need to adjust this parameter,

however in case of long motor cable and/or shielded cable, where there is a

comparatively higher earth capacitance, set this parameter higher to achieve better

motor control performance.

Note that the parameter is indicative and no formula to calculate the suitable value.

Normally, longer the motor cable, bigger the set value. Please adjust depending on your

system.

For 11 and 15kW inverter, it is not needed to set b033.

Specify the run/power-ON warning time (b034).

Rotation restriction related parameters

Rotation direction restriction: b035 – The rotation direction restriction function allows

you to restrict the direction of the motor rotation. This function is effective regardless of

the specification of operation command input device (e.g., control terminal or integrated

operator). If an operation command to drive the motor in a restricted direction is given,

the inverter (display) shows ( ).

Reverse run protection: b046 – The reverse run protection function is effective when

“03 (sensorless vector control)” or “04 (0-SLV)” is specified for the V/F characteristic

selection (A044). For control reasons, especially during motor operation at low speed, the

inverter may output a frequency that instructs the motor to rotate in the direction

opposite to that specified by the operation command.

Torque Limit Function

Torque limit function allows you to limit the motor output when 03 (SLV) is set for the

V/F characteristics set at parameter A044. You can select one of the following modes

with the torque limit selection (b040).

(1) Quadrant-specific setting mode (b040=00)

In this mode, individual torque limit value to be applied to four quadrants (i.e.

forward powering, reverse regeneration, reverse powering and forward

regeneration) are set as the torque limits 1 to 4 (b041 to b044), respectively.

(2) Terminal-switching mode(b040=01)

In this mode, the torque limit values set in the torque limits 1 to 4 (b041 to b044)

are switched from one another according to the combination of the states of torque

limit switch terminals 1 and 2 (TRQ1 and TRQ2) assigned to intelligent input

terminals. A single selected torque limit is valid in all the operating states.

(3) Analog voltage input mode(b040=02)

In this mode, the torque limit value is set by a voltage applied to the control circuit

terminal O. The voltage range 0 to 10V corresponds to the torque limit value range

0 to 200%. A single selected torque limit is valid in all the operating states.

If parameter “40 (TL: whether to enable torque limitation)” has been assigned to any

intelligent input terminal, the torque limit mode selected by the setting of b040 is

enabled only when the TL terminal is turned ON. When the TL terminal is turned OFF,

torque limit settings are invalid, and the maximum torque setting is applied as a torque

limit.

It the TL function has not been assigned to the intelligent input terminal, the torque

limit mode selected by the setting of b040 is always enabled.

Each torque limit value used for this function is expressed as a ratio of the maximum

torque generated when the inverter outputs its maximum current on the assumption

that the maximum torque is 200%.

Note that each torque limit value does not represent an absolute value of torque. The

actual output torque varies depending on the motor.

It the torque limited signal function (TRQ) is assigned to an intelligent output terminal,

the TRQ signal will turn ON when the torque limit function operates.

100% torque is referred to inverter rated current. Absolute torque value is up the motor

to be combined.

・ Controlled Stop Operation at Power Loss

Controlled stop operation at power loss helps avoid tripping or free-running (coasting)

of the motor when power is lost while in run mode. The inverter controls the internal

DC bus voltage while decelerating the motor, and brings the motor to a controlled stop.

Should power be lost while the inverter is in run mode, this function will have the

following effect:

 When the internal DC bus voltage of the inverter comes down to the set level of

B051, the inverter decreases the output frequency by the amount set in B054.

(During this interval the DC bus voltage rises due to regeneration, so does not reach

the UV level.)

 The inverter then continues deceleration according to the value set in B053. If the

DC bus voltage rises up to the set value of B052, the inverter stops deceleration to

avoid OV tripping.

 During this interval, the DC bus voltage decreases again due to lack of input power.

 When the DC bus voltage comes down to the set value of B051, the inverter starts

deceleration according to the set value of B053 again. This process will be repeated

as needed until the motor is brought to a stop.

NOTE: If the DC bus voltage comes down to the UV level during this operation, the

inverter trips with under-voltage and motor will free-run (coast) to a stop.

NOTE: If the set value of B052<B051, then the inverter internally swaps the B052 and

B051 values. However the displayed values are not changed.

NOTE: This function cannot be interrupted until it is completed. So if the power is

restored during this operation, wait until the operation is done (motor stops) and then

Window Comparator, Analog disconnection

The window comparator function outputs signals when the values of analog inputs O

and OI are within the maximum and minimum limits specified for the window

comparator. You can monitor analog inputs with reference to arbitrary levels (to find

input terminal disconnection and other errors).

You can specify a hysteresis width for the maximum-limit and minimum-limit levels of

the window comparator. You can also specify limit levels and a hysteresis width

individually for analog inputs O and OI.

You can fix the analog input data to be applied to an arbitrary value when WCO or

WCOI is output. For this purpose, specify a desired value as the operation level at O/OI

disconnection (b070/b071/b072). When “no” is specified, the analog input data is

reflected as input.

Output values of Odc and OIDc are the same as those of WCO and WCOI, respectively.

Watt-hour related

When the watt-hour monitoring function is selected, the inverter displays the watt-hour

Value displayed by function d015 is expressed as follows:

The watt-hour input gain can be set within the range 1 to 1000 in step of 1.

You can clear the watt-hour data by specifying “01” for the watt-hour clearance function

(b078) and pressing the STR key. You can also clear the watt-hour data at an intelligent

input terminal by assigning parameter “53” (KHC: watt-hour clearance) to the terminal.

Carrier frequency (PWM) related

Carrier frequency adjustment: B083 – The internal

switching frequency

of the inverter

circuitry (also called the

chopper frequency

). It is called the carrier frequency because

the lower AC power frequency of the inverter “rides” the carrier. The faint, high-pitched

sound you hear when the inverter is in Run Mode is characteristic of switching power

supplies in general. The carrier frequency is adjustable from 2.0kHz to 15kHz. The

audible sound decreases at the higher frequencies, but RFI noise and leakage current

may be increased. Refer to the specification derating curves in Chapter 1 to determine

the maximum allowable carrier frequency setting for your particular inverter and

environmental conditions. Refer also to B089 for automatic carrier frequency reduction.

NOTE: The carrier frequency setting must stay within specified limits for

inverter-motor applications that must comply with particular regulatory agencies. For

example, European CE-approved application requires the carrier to be 3kHz or less.

Automatic carrier frequency reduction: B089 – The automatic carrier frequency

reduction automatically reduces the carrier frequency according to the increase in

output current. To enable this function, specify “01” for automatic carrier frequency

reduction selection (b089).

When the output current increases to 60%,

72%, 84%, or 96% of the rated current, this

function reduces the carrier frequency to 12,

9, 6, or 3 kHz, respectively. This function

restores the original carrier frequency when

the output decreases to 5% lower than each

reduction start level.

The rate of carrier frequency reduction is

2kHz per second. The maximum limit of

carrier frequency change by this function is

the value specified for the carrier frequency setting (b083); the minimum limit is 3 kHz.

Note: If 3 kHz or less freq. has been specified for b083, this function is disabled

regardless of the setting of b089.

Miscellaneous Settings

The miscellaneous settings include scaling factors, initialization modes, and others.

This section covers some of the most important settings you may need to configure.

Start frequency adjustment: B082 – When the inverter starts to run, the output

frequency does not ramp from 0Hz. Instead, it steps directly to the

start frequency

(B082), and the ramp proceeds upward from there.

Initialization related: B084, B085, B094, B180 – These functions allow you to restore the

factory default settings. Please refer to “Restoring Factory Default Settings

” in chapter

Stop key enable function: B087 – This function allows you to decide whether the stop

key on the integrated operator is enabled or not.

Dynamic Braking related functions: B090, B095, B096, – These parameters are for using

the internal brake chopper so to get more regeneration torque of the motor.

Cooling Fan Control: B092 – You can select the performance of the cooling fan (if your

inverter model includes a fan). This function controls whether the cooling fan stops or

keeps on running after the inverter stops the motor. This can result in an additional

energy saving and extends fan life.

3−72

Stop Mode / Restart Mode Configuration: B091/B088 – You can configure how the

inverter performs a standard stop (each time Run FWD and REV signals turn OFF).

Setting B091 determines whether the inverter will control the deceleration, or whether

it will perform a free-run stop (coast to a stop). When using the free-run stop selection,

it is imperative to also configure how you want the inverter to resume control of motor

speed. Setting B088 determines whether the inverter will ensure the motor always

resumes at 0 Hz, or whether the motor resumes from its current coasting speed (also

called

active frequency matching

). The run command may turn OFF briefly, allowing

the motor to coast to a slower speed from which normal operation can resume.

In most applications a controlled deceleration is desirable, corresponding to B091=00.

However, applications such as HVAC fan control will often use a free-run stop (B091=01).

This practice decreases dynamic stress on system components, prolonging system life.

In this case, you will typically set B088=01 in order to resume from the current speed

after a free-run stop (see diagram down below: active frequency matching resume). Note

that using the default setting, B088=00, can cause trip events when the inverter

attempts to force the load quickly to zero speed.

NOTE: Other events can cause (or be configured to cause) a free-run stop, such as power

loss (see “Automatic Restart Mode” on page 3-32), or an intelligent input terminal [FRS]

signal. If all free-run stop behavior is important to your application (such as HVAC), be

sure to configure each event accordingly.

3−73

An additional parameter further configures

all instances of a free-run stop. Parameter

B003, Retry Wait Time Before Motor Restart,

sets the minimum time the inverter will

free-run. For example, if B003 = 4 seconds

(and B091=01) and the cause of the free-run

stop lasts 10 seconds, the inverter will

free-run (coast) for a total of 14 seconds

before driving the motor again.

The figure at below right describes how

active frequency matching resume operates.

After waiting the time set in B003, the

inverter tries to catch the speed of the motor

shaft and outputs the speed set in B030. At

this time, if the motor current rises up to the

value set in B028, the inverter decreases the

frequency according to the deceleration time

set in B029, and finally comes to the required

speed. Following are the related parameters

for this control.

Brake Control Function Related

The brake control function allows you to make the inverter control an external brake

used for a lift or other machines. To enable this function, specify “01” (enabling the

brake control function) for the Brake Control Enable (b120). This function operates as

described below.

(1) When the inverter receives an operation command, it starts the output and

accelerates the motor up to the Brake Release Frequency Setting.

(2) After the Brake Release Frequency Setting is reached, the inverter waits for the

braking wait time (b121), and then outputs the brake release signal (BOK). However,

if the inverter output current has not reached the brake release current (b126), the

inverter does not output the brake release signal, but trips and outputs a brake

error signal (BER).

(3) When the braking confirmation signal (BOK) has been assigned to an intelligent

input terminal (that is, when “44” is specified for one of “C001” to “C007”), the

inverter waits for the Brake Wait Time for Confirmation (b124) without accelerating

the motor after receiving the brake release signal. If the inverter does not receive

the braking confirmation signal within the braking confirmation time (b124), it trips

with the braking error signal (BER) output. When the braking confirmation signal

(BOK) has not been assigned to any intelligent input terminal, the Brake Wait Time

for Confirmation (b124) is invalid. In such cases, the inverter proceeds to the

operation described in item (4) after the output of the brake release signal.

(4) After the input of the braking confirmation signal (or the output of the brake release

signal [when the BOK signal function is disabled]), the inverter waits for the Brake

Wait Time for Acceleration (b122), and then starts accelerating the motor up to the

set acceleration frequency.

(5) When the operation command is turned off, the inverter decelerates the motor down

to the braking frequency (b125), and then turns off the brake release signal (BRK).

(1) Time to reach Brake release freq.

(2) Brake Wait Time for Release (b121)

(3) Brake Wait Time for Confirmation (b124)

(4) Brake Wait Time for Acceleration (b122)

(6) When the braking confirmation signal (BOK) has been assigned to an intelligent

input terminal (that is, when “44” is specified for one of “C001” to “C007”), the

inverter waits, after turning off the brake release signal, until the braking

confirmation is turned off at least for the Brake Wait Time for Confirmation (b124)

without decelerating the motor. If the braking confirmation signal is not turned off

within the Brake Wait Time for Confirmation (b124), the inverter trips with the

braking error signal (BER) output. When the braking confirmation signal (BOK)

has not been assigned to any intelligent input terminal, the Brake Wait Time for

Confirmation (b124) is invalid. In such cases, the inverter proceeds to the operation

described in item (7) after the brake release signal is turned off.

(7) After the braking confirmation signal (or the brake release signal [when the BOK

signal function is disabled]) is turned off, the inverter waits for the Brake Wait Time

for Stopping (b123), and then starts decelerating the motor down to 0Hz.

NOTE: The above timing chart shows the operation on the assumption that the braking

confirmation signal “44” (BOK) is assigned to one of the terminal 1 to 7 (C001~C007). If

the BOK signal is not assigned to any terminal, the Brake Wait Time for Acceleration

(b122) begins when the brake release signal is turned on, and the Brake Wait Time for

Stopping (b123) begins when the brake release signal is turned off.

When using the brake control function, assign the following signal functions to

intelligent input and output terminals as needed.

 To input a signal indicating that the brake is released from the external brake to the

inverter, assign the braking confirmation signal (44: BOK) to one of the terminal 1~7

(C001~C007)

 Assign the brake release signal (19: BRK), which is a brake-releasing command, to

one of the output terminal 11~12 (C021~C022). To output a signal when braking is

abnormal, assign the brake error signal (20: BER) to an output terminal.

bus voltage in case of deceleration. DC

bus voltage rises due to regeneration

during deceleration. When this

function is activated (B130=01 or 02),

inverter controls the deceleration time

so that the DC bus voltage not to go up

to the overvoltage trip level, and leads

“C” Group: Intelligent Terminal Functions

The seven input terminals [1], [2], [3], [4], [5], [6], and [7] can be configured for any of 72

different functions. The next two tables show how to configure the seven terminals. The

inputs are logical, in that they are either OFF or ON. We define these states as OFF=0,

and ON=1.

The inverter comes with default options for the seven terminals. These settings are

initially unique, each one having its own setting. Note that European and US versions

have different default settings. You can use any option on any terminal, and even use

the same option twice to create a logical OR (though usually not required).

NOTE: Terminals [3] and [4] have the ability to be logical inputs, and to be safety inputs

in case of safe stop function is selected.

NOTE: Terminal [5] has the ability to be a logical input, and to be an analog input for a

thermistor device when PTC function (option code 19) is assigned to that terminal.

Input Terminal Configuration

Functions and Options – The

function codes

in the following table let you assign one of

seventy-two options to any of the seven logic inputs for the XJ200 inverters. The

functions C001 through C007 configure the terminals [1] through [7] respectively. The

“value” of these particular parameters is not a scalar value, but it is a discrete number

that selects one option from many available

options

For example, if you set function C001=00, you have assigned option 00 (Forward Run) to

terminal [1]. The option codes and the specifics of how each one works are in Chap. 4.

Intelligent Input Terminal Overview

Each of the seven intelligent terminals may be assigned any of the options in the

following table. When you program one of the option codes for terminal assignments

C001 to C007, the respective terminal assumes the function role of that option code. The

terminal functions have a symbol or abbreviation that we use to label a terminal using

that function. For example, the “Forward Run” command is [FW]. The physical label on

the terminal block connector is simply 1, 2, 3, 4, 5, 6, or 7. However, schematic examples

in this manual also use the terminal symbol (such as [FW]) to show the assigned option.

The option codes for C011 to C017 determines the active state of the logical input (active

high or active low).

sec.), the [RS] (reset) terminal affects the ON-to-OFF transition slightly. Normally (with

using OFF delays), the [RS] input causes the motor output and the logic outputs to turn

OFF together, immediately. However, when any output uses an OFF delay, then after

the [RS] input turns ON, that output will remain ON for an additional 1 sec. period

(approximate) before turning OFF.

Low Load Detection Parameters

The following parameters work in

conjunction with the intelligent output

function, when configured. The output

mode parameter (C038) sets the mode of

the detection at which the low load

detection signal [LOC] turns ON. Three

kinds of modes can be selected. The

detection level parameter (C039) is to set

the level of the low load.

This function is for generating an early

warning logic output, without causing

either a trip event or a restriction of the

motor current (those effects are available

on other functions).

Output Function Adjustment Parameters

Overload Warning Output - The following

parameters work in conjunction with the

intelligent output function, when configured.

The overload level parameter (C041) sets the

motor current level at which the overload

signal [OL] turns ON. The range of setting is

from 0% to 200% of the rated current for the

inverter. This function is for generating an

early warning logic output, without causing

either a trip event or a restriction of the

motor current (those effects are available on

other functions).

Frequency Arrival Output - The frequency

arrival signal, [FA1] or [FA2], is intended to

indicate when the inverter output has

reached (arrived at) the target frequency.

You can adjust the timing of the leading and

trailing edges of the signal via two

parameters specified to acceleration ad

deceleration ramps, C042 and C043. Refer

also to chapter 4.

PID FBV Output - The Error for the PID

loop is the magnitude (absolute value) of

the difference between the Set point

(desired value) and Process Variable

(actual value). The PID output deviation

signal [OD] (output terminal function

option code 04) indicates when the error

magnitude has exceeded a magnitude you

define.

Over/Under-torque Output – The inverter outputs the over/under-torque signal when it

detects that the estimated motor output torque exceeds the specified level. To enable

this function, assign parameter “07” (OTQ: over/under-torque signal) to an intelligent

output terminal. Over-torque or under-torque can be selected by function C054.

This function is effective only when the V/F characteristic curve selection “A044” or

“A244” is the sensorless vector control or 0Hz range sensorless vector control. With any

other V/F characteristic curve is selected, the output of the OTQ signal is unpredictable.

When using the inverter for a lift, use the OTQ signal as the trigger to stop braking.

Use the frequency arrival signal as the trigger to start braking.

Zero speed detection Output – The inverter outputs the 0Hz speed detection signal

when the inverter output frequency falls below the threshold frequency specified in the

zero speed detection level (C063).

To use this function, assign parameter “21” to one of the intelligent output terminals

[11] to [12] (C021 to C022), or to the alarm relay output terminal (C026).

This function applies to the inverter output frequency when the V/F characteristic

curve selection is based on the constant torque (VC), reduced torque (VP), free-V/F,

sensorless vector control, or 0Hz range sensorless vector control.

Heat Sink Overheat Warning Output – The inverter monitors the temperature of its

heat sink, and outputs the heat sink overheat warning (OHF) signal when the

temperature exceeds the heat sink overheat warning level specified in parameter C064.

Motor Constants Selection

Adjust the motor constant settings to the motor to be driven by the inverter.

When using a single inverter to drive multiple motors in the control mode based on VC,

VP, or free V/F characteristics, calculate the total capacity of the motors, and specify a

value close to the total capacity for the motor capacity selection (H003/H203).

When the automatic torque boost function is used, the motor constant settings that do

not match with the motor may result in a reduced motor torque, or unstable motor

operation.

You can select the motor constants that are used when the control mode is the

sensorless vector control (hereafter “SLV”) from the following three types.

(1) Motor constants of Hitachi standard induction motor

When H002/H202=00, motor constants in H020/H220 to H024/H224 are taken. The

initial values in H020/H220 to H024/H224 are Hitachi standard motor's values.

(2) Motor constants obtained by off-line auto-tuning

When H002/H202=02, motor constants in H030/H230 to H034/H234 are taken, which are

obtained by off-line auto-tuning.

(3) Arbitrarily set motor constants

In above (1) and (2) cases, motor constants can be adjusted manually. According to

value of H002/H202, change motor constants in H020/H220 to H024/H224 or H030/H230 to

H034/H234 if necessary.

*1) Convert the inertia (J) to the motor shaft value. Bigger J value will result in a quicker

in motor response and quicker in torque increase. Smaller J value will result in the

opposite way.

*2) In the SLV modes, inverter may give out reverse to given operation command in the

low speed range as a nature of those controls. In case there is a specific inconvenience

for example reverse rotation damages the machine, enable the reverse run protection

(b046).

3−107

Sensorless Vector Control

This sensorless vector control enables the inverter to accurately operate the motor with

a high starting torque, even at low speed. It estimates and controls the motor speed and

output torque based on the inverter output voltage, output current, and the set motor

constants on the inverter. To use this function, specify “03” for the V/F characteristic

curve selection (A044/A2444).

In prior to use this function, be sure to make optimum setting of the motor constants,

which is described before.

When using this function, observe the following precautions:

(1) If you use the inverter to drive a motor of which the capacity is two class lower than

the maximum applicable capacity of the inverter, you may not be able to obtain

adequate motor characteristics.

(2) If you cannot obtain the desired characteristics from the motor driven under the

SLV control, readjust the motor constants according to the symptom, as described in

the table below.

Note 1) When driving a motor of which the capacity is one class lower than the inverter,

adjust the torque limit (b041 to b044) so that the value “α” calculated by the

expression below does not exceed 200%. Otherwise, the motor may not be burnt.

α = “torque limit” x (inverter capacity) / (motor capacity)

(Example) When the inverter capacity is 0.75kW and the motor capacity is 0.4kW,

the torque limit value is calculated as follows, based on the

assumption that the value α should be 200%:

Torque limit (b041 to b044) = α x (motor capacity) / (inverter capacity)

= 2.0 x (0.4kW)/(0.75kW) = 106%

Auto-tuning Function

The WJ200 inverter has auto-tuning function to get suitable motor control performance

by measuring the motor constants automatically. Auto-tuning is effective only

sensorless vector control.

Auto-tuning with motor stop (H001=01)

Motor does not rotate while auto-tuning. If rotating motor could give harm to your

application, use this mode. But the motor constant I

(no-load current) and J

(inertia) are not measured and remain unchanged. (I

can be monitored in 50Hz of

V/f operation.)

Auto-tuning with motor rotation (H001=02)

Motor rotates according to a special operation pattern while auto-tuning. However,

the torque during auto-tuning is not sufficient, which may cause a problem in the

load (for example, a lift may slide down). See below instruction 7)-d).

When using auto-tuning function, follow the instructions below.

1) When using a motor which constants are unknown, execute offline auto-tuning to obtain the

constants.

2) When the motor constant selection (H002/H202) is Hitachi std. motor (01), the initial values in

H020/H220 to H024/H224 are Hitachi standard motor's values. If Hitachi std. motor is used, full

performance is achieved without auto-tuning in most cases.

3) The motor constant data is corresponding to one-phase of Y (star) connection for 50Hz.

4) Set base frequency (A003) and AVR voltage (A082) according to the motor specifications. If the

motor voltage is other than the alternatives, set V/f gain (A045) according to below formula.

“motor voltage (A082)” × “output voltage gain (A045)” = “motor rated voltage”

5) Proper motor constants are obtained only when the same size or one size lower motor is used.

If other size of motor is connected, proper values may not be obtained or auto-tuning operation

may not be completed. In this case, press STOP/RESET key, then error code will be displayed.

6) Be sure to disable DC braking setting (A051=00) and simple positioning selection (P012=00),

otherwise motor constants are not measured properly.

7) Be sure to deactivate ATR terminal (52:Enable torque cmd. input), otherwise motor constants

are not measured properly.

8) If auto-tuning with motor rotation (H001=02) is used, check the followings points.

a) The motor rotates up to 80% of base frequency. Check if it is no problem for the application.

b) The motor should not be driven by any other external force.

c) All the brakes should be released.

d) During auto-tuning, insufficient torque may cause a problem in the load (for example, a lift

may slide down). In this case, remove the motor from the machine or other load, and

perform auto-tuning with the motor alone. The measured inertia J is based on the motor

alone. To apply the data, add the moment of inertia of the load machine to the measured J

data after converting the moment of inertia to the motor shaft data.

e) If the application is with limitat

ion (e.g. lift or boring machine), the allowable rotation limit

may be exceeded in auto-tuning, and the machine may be damaged.

9) Even when “01 (auto-tuning without motor rotation)” is selected, the motor could rotate

slightly during auto-tuning.

10) When performing the auto-tuning with one lower size of motor, enable the overload restriction

function, and set the overload restriction level to 150% of the rated current of the motor.

11) When deceleration over-voltage suppress integral time (b134) is small, auto-tuning may result

3−109

in over-voltage trip. In this case, increase b134 and retry the auto-tuning.

12) To execute auto-tuning, be sure to set the output frequency (F001) larger than starting

frequency (b082) regardless with or without rotation.

3−110

Off-line auto-tuning procedure (with motor rotation)

(Note 2) After auto-tuning is completed, be sure to set 01 in H002/H202, otherwise measured data is

not effective.

(Note 3) Speed "X" of above (5) depends on accel/deceleration time. (T: Larger time of accel or

deceleration time)

0 < T < 50 [s] : X=40%

50 ≤ T < 100 [s] : X=20%

100 ≤ T [s] : X=10%

(Note 4) If auto-tuning is failed, try to execute again.

(Note 5) If the inverter trips during the auto-tuning, the auto-tuning is interrupted. After removing

the cause of trip, retry auto-tuning from the beginning.

(Note 6) If inverter is stopped during auto-tuning by stop command (by STOP key or deactivate RUN

input), measured constants could remain. Be sure to execute auto-tuning again.

(Note 7) If auto-tuning is attempted in free V/f setting, auto-tuning will fail with error display.

Simple positioning setting

- Set “03” in [EA] selection (P003), then pulse train input is used as feedback signal from encoder.

- Set "02" in simple positioning selection (P012), then simple positioning is enabled. (If "00" is set, "V/f

control with FB" is enabled. Please refer to xx for further information.

- Up to 8 position data are commanded by combination of 3 input terminals configured as CP1 to

CP3.

- Besides positioning input, RUN command (FW,RV) is necessary. Since rotation direction does not

matter for positioning, both FW and RV work as RUN command.

- Positioning speed depends on frequency source (A001).

- More than four digits are required for positioning data, but only four higher digits are displayed.

In the simple positioning mode, the inverter runs the motor until the machine reaches

the target position according to the following settings, and then stops the motor with

DC braking.

<1> Position setting

<2> Speed setting (frequency setting)

<3> Acceleration and deceleration time

(DC braking state is held until RUN command is turned off.)

n simple positioning mode, the frequency and acceleration/deceleration are according to current

settings as same as normal operation.

- Depending on DC braking and creep speed setting, positioning may go off the point.

- If the position value specified by the position setting is small, the inverter may decelerate the

motor for positioning before its speed reaches the speed setting.

- In simple positioning mode, the rotation direction setting (FW or RV) of the operation

command is ignored. The operation command simply functions as the signal to run or stop the

motor. The motor runs in the forward direction when the value of “target position” –(minus)

“current position” is positive, or in the reverse position when the value is negative.

- The position at power up is home position (Position data = 0). If power is removed, current

position data is lost.

- When the operation command is turned on with 0 specified as the position setting, positioning

is completed (with DC braking) without running the motor.

- Specify “03 (only to reset a trip)” for reset mode selection (C102). If a value other than “03” is

specified to C102, the current position counter will be cleared when the inverter reset terminal (or

reset key) is turned on. Be sure to specify “03” for reset mode selection (C102) if you intend to use

the value of the current position counter for operation after recovering the inverter from tripping

by turning on the reset terminal (or reset key).

- If the PCLR function is assigned to a input terminal, turning it on to clear the current position

counter.

- In simple positioning mode, ATR terminal is invalid. (Torque control does not work.)

- If current position is out of the set range, inverter will be tripped (E83) and coasting status.
