Main Control Function

Control Mode: V/F, Sensorless Vector Control (SVC), Torque control 
Overload Capacity: 60s with 150% of rated current, 10s with 180% of rated current
Speed Adjusting Range: 1:100 (SVC)
Carrier Frequency: 1kHz – 15.0kHz
Frequency reference source: keypad, analog input, HDI, serial communication, multi-stage speed, simple PLC and PID setting. The combination of multi-modes and the switch between diffrent modes can be realized
PID Control Function
Simple PLC, Multi-Steps Speed Control Function: 16 stages speed can be set
Traverse Control Function
None-Stop when instantaneous power off
Speed Trace Function: Smoothly start the running motor
QUICK/JOG Key: User defined shortcut key can be realized
Automatic Voltage Regulation Function (AVR)
Automatically keep the output voltage stable when input voltage flucuating
Fault protections: Protect from over current, over voltage, under voltage, over temperature, phase failure, over load etc.
