Item
Sinusoidal PWM control
Setting between 0.01 to 500Hz. Default max. frequency is set to 0.01 to 60Hz.
Maximum frequency adjustment (30 to 500Hz)
0.01Hz: operation panel input (60Hz base),
0.02Hz: analog input (60Hz base, 11 bit/0 to 10Vdc)
Analog input: ±0.2% of the maximum output frequency (at 25±10°C)
Digital input: ±0.01%±0.022Hz of the output frequency
V/f constant, square reduction torque control, automatic torque boost, vector calculation control, base
frequency adjustment 1 and 2 (25 to 500Hz), V/f 5-point arbitrary setting, torque boost adjustment (0 to
30%), start frequency adjustment (0 to 10Hz), stop frequency adjustment (0 to 30Hz)
3kΩ potentiometer (possible to connect to 1 to 10kΩ-rated potentiometer)
0 to 10Vdc (input impedance Zin: 30kΩ)
0 to ±10Vdc (Zin: 22kΩ)
4 to 20mAdc (Zin:242Ω)
The characteristic can be set arbitrarily by two-point setting. Compliant with 6 types of input; analog input
(RR, VI/II, RX, RX2), pulse input and binary/BCD input (*RX2, binary/BCD input: optional)
3 places. Setting of jump frequency and width.
Upper limit frequency: 0 to max. frequency, lower limit frequency: 0 to upper limit frequency
Adjustable between 1.0 to 16kHz.
Adjustment of proportional gain, integral time, differential time and delay filter
0.01 to 6000 sec. Selectable from among acceleration/deceleration. times 1 and 2. Automatic
acceleration/deceleration function. S-pattern acceleration/deceleration 1 and 2 pattern adjustable.
Adjustment of braking start frequency (0 to 120Hz), braking (0 to 100%) and braking time (0 to 20 sec.).
With emergency stop braking function and motor shaft fix control function.
With F-CC closed to forward run, with R-CC closed to reverse run, with both closed to reverse run. With
ST-CC opened to coast stop. Emergency stop by panel operation or terminal board.
Jog mode, if selected, allows jog operation from the operation panel
Jog run operation by terminal board is possible by setting the parameters.
By changing the combination of open/close between S1, S2, S3, RR/S4-CC, set frequency + 15-speed
operation.
Selectable between acceleration/deceleration time, torque limit and V/f by set frequency.
Capable of restarting after a check of the main circuit elements in case the protective function is
activated. Max. 10 times selectable arbitrarily. Waiting time adjustment (0 to 10 sec.)
Automatic load reduction control at overloading. (Default: OFF)
The cooling fan will be stopped automatically to assure long life when unnecessary.
However, the fan inside the drive will always runs.
Key prohibition selectable for frequency setting, etc. All key operations can also be prohibited.
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 switch operation by commercial power source or inverter
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 [Note 5], undervoltage, momentary power failure (15ms 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 dynamic braking resistance, fin overheat, emergency stop
Switchable between standard motor/constant torque VF motor, adjustment of overload protection and
stall prevention level.
Reset by 1a contact closed (or 1b contact opened), or by operation panel. Or power source OFF/ON.
This function is also used to save and clear trip records.
