Note:
*1 Fuji 4-pole standard motor. At the selection of the inverter rating, consider not only the rating capacity(kW) is enough but also inverter output current is larger than selected the motor's nominal current.
*2 Rated capacity is calculated by assuming the output rated voltage as 440 V.
*3 The output voltage cannot exceed the power supply voltage.
*4 W
hen the carrier frequency (F26) is set to below value or higher, the inverter is sure to be necessary to derate their nominal current.
HHD spec.---type 0002 to 0012 : 8kHz, type 0022 to 0168 : 10kHz, type 0203 to 0590 : 6kHz
HND spec.---type 0002 to 0012 : 8kHz, type 0022 to 0059 : 10kHz, type 0072 to 0168 : 6kHz, type 0203 to 0590 : 4kHz HD,ND spec.---All type : 4kHz
The rated output current at HD/ND spec. is decreased 2% for every 1 °C (1.8 °F) when ambient temperature is +40 °C (+104 °F) or more.
*5 T he value is calculated assuming that the inverter is connected with a power supply with the capacity of 500 kVA (or 10 times the inverter capacity if the inverter capacity exceeds 50 kVA) and %X is 5%. Be sure to use the DCR when
applicable motor capacity is 75kW or above.
*6 Obtained when a DC reactor (DCR) is used.
*7 Average braking torque for the motor running alone. (It varies with the efficiency of the motor.)

*8 Voltage unbalance (%) =(Max. voltage (V) - Min. voltage (V))/Three -phase average voltage (V) × 67 (IEC 61800 - 3) If this value is 2 to 3%, use an optional AC reactor (ACR).
*9 HND spec. of the type 0007 and 0012: allowable ambient temperature 40 °C (+104 °F) or less. The rated output current at HND spec. is decreased 1% for every 1 °C (1.8 °F) when ambient temperature is +40 °C (+104 °F) or more.

During forced stop operation, S-curve acceleration/deceleration is disabled.
Frequency

and lower limit
frequencies)

• “Continue to run” or “Decelerate to a stop” selectable when the reference frequency drops below the lower limit.
Frequency/PID
command bias

(setting range: 0 to ±100%).
Analog input

• Filter: Setting range from 0.00 s to 5.00 s • Polarity selection (±/+)
Jump frequency

Jogging operation
• Operation with key (standard keypad), or key (multi-function keypad), or digital input signal FWD or REV
(Exclusive acceleration/deceleration time setting, exclusive frequency setting)
Auto-restart after
momentary power
failure
• Trip immediately: Trip immediately at the time of power failure.
•Trip after a recovery from power failure: Coast to a stop at the time of power failure and trip when the power is recovered.
•Trip after decelerate-to-stop: Deceleration stop at power failure, and trip after stoppage
• Continue to run: Operation is continued using the load inertia energy.
•S tart at the frequency selected before momentary power failure: Coast-to-stop at power failure and start after power recovery at the frequency
selected before momentary stop.
• Start at starting frequency: Coast-to-stop at power failure and start at the starting frequency after power recovery.
•S tart at the frequency searched at the time of power recovery: Coast-to-stop at power failure, search for the idling motor speed, and restart the
motor.
Hardware current
limiter
Limits the current by hardware to prevent an overcurrent trip from being caused by fast load variation or momentary power failure, which cannot be
covered by the software current limiter. This limiter can be canceled.
Operation by
commercial power
supply
With commercial power selection commands (SW50, SW60), the inverter outputs 50/60 Hz.
Slip compensation
• Compensates for decrease in speed according to the load • Possible to set constants for the response of slip compensation.
Droop control
•Decreases the speed according to the load torque.
Control
Torque limiter
Torque current
limiter
Control output torque so that output torque is preset limiting value or less.
• Switchable between 1st and 2nd torque limit values
• Torque limit and Torque current limit are selectable.
IMPG-VC
• Torque limit by analog input.
PM-SVC
Software current
limiter
Automatically reduces the frequency so that the output current becomes lower than the preset operation level. This limiter can be canceled.
Overload stop
If the detected torque or current exceeds the preset value, the inverter decelerates the motor to a stop or causes the motor to coast to a stop.
PID control
• PID processor for process control/dancer control • Normal operation/inverse operation
•PID command: Keypad, analog input (from terminals [12], [C1] (C1 function) and [C1] (V2 function)), multistep frequency (3 steps), RS-485
communication
• PID feedback value: Analog input (from terminals [12], [C1] (C1 function) and [C1] (V2 function))
• Alarm output (absolute value alarm, deviation alarm) • Low liquid level stop function (pressurized operation possible before low liquid level stop)
• Anti-reset wind-up function • PID output limiter • Integration reset/hold
Auto search for
idling motor speed
The inverter automatically searches for the idling motor speed and starts to drive it without stopping it. Motor parameters require tuning. (Offline
tuning)
Automatic
deceleration
• If the DC link bus voltage or calculated torque exceeds the automatic deceleration level during deceleration, the inverter automatically prolongs
the deceleration time to avoid overvoltage trip. (It is possible to select forcible deceleration actuated when the deceleration time becomes three
times longer.)
•If the calculated torque exceeds automatic deceleration level during constant speed operation, the inverter avoids overvoltage trip by increasing
the frequency.
