Detail specifications
Keypad operation: key and
Setting with potentiometer (external potentiometer: 1 to 5 kΩ 1/2 W)
Setting with 0 to ± 5 Vdc.
Setting with 0 to ± 10 Vdc.
Setting with 4 to 20 mAdc.
0 to +10 Vdc / 0 to 100% can be switched to +10 to 0 Vdc / 0 to 100%
externally.
4 to 20 mAdc / 0 to 100% can be switched to 20 to 4 mAdc / 0 to 100%
externally.
An external signal can be used to control the UP or DOWN command.
Up to 16 different frequencies can be selected by digital input signals.
Link operation : RS485 (Standard)
Profibus-DP,Interbus-S,DeviceNet,Modbus Plus, CAN open (Option)
Variable setting in 0.01 to 3600s range. (2 sets of time can be set internally for
each of acceleration and deceleration.)
Linear, S-curve (weak,strong), Non-linear available.
The high and low frequency limits can be set variably in a 0 to 100% range in Hz.
Can be set variably in -400 to 400 Hz range.
Can be set variably in a 0 to 200% range.
Three jump frequencies and jump width (0 to 30 Hz) can be set.
Operation without shock is possible.
The motor speed can be detected after power recovery so that the motor is
started at the speed.
The load during regular operation can be detected for the control of the
frequency. The compensation value can be set variably in a 0.00 to +15.00 Hz
range to the rated frequency.
The load during regular operation can be detected for the control of the
frequency. The compensation value can be set in a -9.9 to 0.0 Hz range to the
rated frequency. (Speed droop characteristics)
When the load torque in the driving or braking mode exceeds the setting, the
frequency is controlled to control the load torque to an almost constant level.
The limiting torque can be set 20 to 200% and the driving and braking torque
values can be independently set.
A second set of torque limits can be set.
