(Link operation) Link operation : RS485 (Standard)
Profibus-DP,Interbus-S,DeviceNet,Modbus Plus, CAN open (Option)
Acceleration / Variable setting in 0.01 to 3600s range. (2 sets of time can be set internally for
deceleration time each of acceleration and deceleration.)
(Mode select) Linear, S-curve (weak,strong), Non-linear available.
Frequency limiter The high and low frequency limits can be set variably in a 0 to 100% range in Hz.
Bias frequency Can be set variably in -400 to 400 Hz range.
Gain Can be set variably in a 0 to 200% range.
(frequency setting)
Jump frequency Three jump frequencies and jump width (0 to 30 Hz) can be set.
control
Rotating motor Operation without shock is possible.

(Flying start)
Auto-restart after The motor speed can be detected after power recovery so that the motor is
momentary power started at the speed.

Slip compensation The load during regular operation can be detected for the control of the
control frequency. The compensation value can be set variably in a 0.00 to +15.00 Hz
range to the rated frequency.
Droop operation 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)
Torque limiter 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.
