Torque boost

Automatically torque boost;Automatically determine the lifting torque based on the output current and combined with motor parameters manually torque boost: 0.0%~30.0%

Automatic current and voltage limiting

It can automatically detect the stator current and voltage of the motor during acceleration, deceleration, or stable operation, and suppress them within the allowable range based on a unique algorithm, minimizing the possibility of system fault tripping

Senseless vector control

Voltage frequency characteristics

Automatically adjust the output voltage frequency ratio based on motor parameters and unique algorithms

Torque characteristics

Starting Torque:

150% rated torque at 3.0Hz (V/F control)

Steady-state accuracy at operating speed: ≤±0.2% rated synchronous speed

Speed Fluctuation: ≤±0.5% of rated synchronous speed

Torque response: ≤20ms (sensorless vector control)

Self-measurement of motor parameters

Without any limitations, automatic parameter detection can be completed under both static and dynamic conditions of the motor to achieve the best control effect

Current and voltage suppression

Full process current closed-loop control, completely avoiding current surge, with complete overcurrent and overvoltage suppression function

Control characteristics

Under voltage suppression during operation

Especially for users with low grid voltage and frequent fluctuations in grid voltage, even within the allowable voltage range, the system can maintain the longest possible operating time based on unique algorithms and residual energy allocation strategies
