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.
Freq. setting

Pulse input
0~10kHz (Upper limit and Lower limit can be selected)
Startup signal
FWD, REV, startup signal can be selected and self-keep (Three line control).
Timer and Counter
Embedded one timer and one counter ,which will help the system’s integration.
Multi-speed control function/
Wobble frequency
Seven steps programmable multi-speed control at most, every step’s running direction, running time can be set respectively. In external terminal control, It reaches 15 steps, and there are 6 kind of running modes. Include wobble frequency.
Built-in
PID control
Common PID
Expediently compose the simple control system without accessional PID controller.
Special for water supply
(Need accessories)
Make it possible to construct the constant-pressure water-supply system of 4 pumps switch at most, which includes the following functions: pressure upper or Lower limit alarm, Sleep or wake, Timing water-supply etc. multi kind running mode.
Running function
Setting the upper and lower limit of frequency, frequency jump-running, reversal running limit, slip frequency compensation, auto constant-voltage running, RS485 communication frequency increment and decrement control, fault self-restore running, multi inverter coupled running.
