V/F Curve

(Voltage-Frequency character)

Base frequency can be set from 5~500Hz arbitrarily, and there are three kinds of curve: constant torque ,Dec torque 1 and Dec torque 2.

Torque Boost

Manual Setting: 0~20% of rated output, Auto-boost: Automatically boost torque according to output current.

Auto Energy-saving running

Adjust output voltage and slip compensation properly according to output current, which will make the motor working in highest efficiency.

Control

character

Acc./Dec. time setting

0.1~6000 seconds can be set continuously, and S type and line type can be selected.

Braking

Dynamic braking

Over 75% (External braking resistor)

DC braking

It is selected respectively at start and stop, and its frequency is 0~15Hz, the action voltage is 0~15%, and the action time is 0~20.0 second or act continuously.

Auto current-limiting function

Fast auto current-limiting function ensures not to occur the over-current during the accelerate process or under the impact load.

Overvoltage prevention

Ensure not over-voltage in Dec process.

Low noise running

Carrier freq. can be adjusted continuously form 1.5KHz to 15.0KHz, which can reduce the motor’s noise furthest.

Speed tracking restart

It can realize the smoothness restart and instantaneous stop then restart function.
