Torque Lifting
Automatic torque lifting: to lift the torque automatically
according to the output current.
Hand-operated torque lifting: Range: 1~30%
Slip Compensation
Setting range: 0~20%. The inverter output frequency
can be auto-regulated within this range according to the
motor load so as to reduce the speed variation of the
motor due to load fluctuation.

This can realize the output of DC 0~10V signal,
frequency, current and other physical quantity.
Dynamic braking
With an external braking resistor, the maximum braking
torque may reach 100%.
This can be selected when the motor starts or stops with
the action frequency of 0~20Hz action voltage level of
0~20% and actuation time of 0~30 sec., and this value
can be set in sequence.
