Sinusoidal PWM control
Adjustable within the range of 50 - 330 V (240 V class) and 50 - 660 V (480 V class) by correcting the supply voltage
Setting between 0.01 - 590 Hz. Default frequency is set to 0.01-50/60 Hz.
Maximum frequency adjustment (30 to 590Hz)
0.01 Hz: operation panel input (60 Hz base),
0.03 Hz: analog input (60 Hz base, 11 bit/0 - 10 Vdc)
Analog input: ±0.2% of the maximum output frequency (at 25±10°C)
Digital input: ±0.01%±0.022 Hz of the output frequency
V/f constant, variable torque, automatic torque boost, vector control, base frequency adjustment 1, 2, 3, and 4 (15 - 590
Hz), V/f 5-point arbitrary setting, torque boost adjustment (0 - 30%), start frequency adjustment (0 - 10 Hz), stop
frequency adjustment (0 - 30 Hz)
3 kΩ potentiometer (possible to connect to 1 - 10 kΩ-rated potentiometer)
0 - 10Vdc (input impedance Zin: 31.5 kΩ)
-10 to +10 Vdc (Zin: 31.5 kΩ)
4 - 20 mAdc (Zin: 250 Ω)
The characteristic can be set arbitrarily by two-point setting. Compliant with 7 types of input; analog input (RR, RX, II,
AI4, AI5), and pulse input (S4, S5)
Three frequency can be set. Setting of jump frequency and width.
Upper limit frequency: 0 to max. frequency, lower limit frequency: 0 to upper limit frequency
Frame size A1 to A4: adjustable between 1.0 - 16 kHz
Frame size A5 to A8: adjustable between 2.5 - 8 kHz
Adjustment of proportional gain, integral time, differential time and delay filter. Multi PID and external PID control.
Voltage command input specification: -10 - +10 Vdc
Current time (Year, month, date, hour, minute), Timezone, Daylight saving time, 4 working days and 20 holidays can be
set by parameters.
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.
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 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, if selected, allows jog operation from the operation panel
Jog run operation by terminal block is possible by setting the parameters.
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.
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.)
Automatic load reduction control at overloading. (Default: OFF)
The cooling fan will be stopped automatically to assure long life when unnecessary.
Key lock selectable between STOP key only, MODE key only, etc. All key operations can be locked.
Possible to keep the motor running using its regenerative energy in case of a momentary power failure. (Default: OFF)
Possible to restart the motor in coasting in accordance with its speed and direction. (Default: OFF)
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.
Possible to switch operation by commercial power supply or inverter
Increases the operating efficiency of the machine by increasing the rotational speed of the motor when it is operated
under light load.
When two or more inverters are used to operate a single load, this function prevents load from concentrating on one
inverter due to unbalance.
External input signal adjustment is possible to the operation frequency command value.
Stall prevention, current limit, overcurrent, overvoltage, short circuit on the load side, ground fault on the load side
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
Switchable between standard motor/constant torque motor, adjustment of overload protection and stall prevention level.
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.
