Item Specification
Control specification
Control system Sinusoidal PWM control
Output voltage adjustment Adjustable within the range of 50 - 330 V (240 V class) and 50 - 660 V (480 V class) by correcting the supply voltage

Real time clock
Current time (Year, month, date, hour, minute), Timezone, Daylight saving time, 4 working days and 20 holidays can be
set by parameters.
Operation specifications
Acceleration/deceleration time
0.01 - 6000 sec. Selectable from among acceleration/deceleration. times 1, 2, 3 and 4. Automatic acceleration/
deceleration function. S-pattern acceleration/deceleration 1 and 2 pattern adjustable.
DC braking
Adjustment of braking start frequency (0 - <FH>Hz), braking (0 - 100%) and braking time (0 - 25.5 sec.). With emergency
off braking function and motor shaft fix control function.
Forward run/reverse run
*1
Forward run with ON of the terminal [F], Reverse run with ON of the terminal [R] (Default setting). Coast stop with OFF
of the terminal assigned Stad-by function. Emergency off by panel operation or terminal.
Jog run
*1
Jog run, if selected, allows jog operation from the operation panel
Jog run operation by terminal block is possible by setting the parameters.
Preset speed operation
*1
By changing the combination of the terminals [S1], [S2], [S3], [S4], [S5] set frequency + 31-speed operation.
Selectable between acceleration/deceleration time, torque limit and V/f by set frequency.
Retry
Capable of restarting after a check of the power circuit elements in case the protective function is activated. Max. 10
times selectable arbitrarily. Waiting time adjustment (0 - 10 sec.)
Soft stall Automatic load reduction control at overloading. (Default: OFF)
Cooling fan ON/OFF The cooling fan will be stopped automatically to assure long life when unnecessary.
Operation panel key operation
ON/OFF control
Key lock selectable between STOP key only, MODE key only, etc. All key operations can be locked.
Regenerative power ride-through
control
Possible to keep the motor running using its regenerative energy in case of a momentary power failure. (Default: OFF)
Auto-restart operation Possible to restart the motor in coasting in accordance with its speed and direction. (Default: OFF)
Simplified pattern operation
Possible to select each 8 patterns in 2 groups from 15-speed operation frequency. Max. 16 types of operation possible.
Terminal operation/repeat operation possible.
Commercial inverter switching Possible to switch operation by commercial power supply or inverter
Light-load high-speed operation
Increases the operating efficiency of the machine by increasing the rotational speed of the motor when it is operated
under light load.
Droop function
When two or more inverters are used to operate a single load, this function prevents load from concentrating on one
inverter due to unbalance.
Override function External input signal adjustment is possible to the operation frequency command value.
Protective function
Protective function
Stall prevention, current limit, overcurrent, overvoltage, short circuit on the load side, ground fault on the load side
*5
,
undervoltage, momentary power failure (15 ms or more), non-stop control at momentary power failure, overload
protection, arm overload at starting, overcurrent on the load side at starting, overcurrent and overload at braking resistor,
overheat, emergency off
Electronic thermal characteristic Switchable between standard motor/constant torque motor, adjustment of overload protection and stall prevention level.
Reset
Reset by 1a contact closed (or 1b contact opened), or by operation panel. Or power supply OFF/ON. This function is
also used to save and clear trip records.
