frequency

characteristics)

Three ways: the first is a linear torque characteristic

curve, the second is a square torque characteristic

curve, and the third is a user-set V/F curve

torque boost

Manual setting: 0.0 to 30.0% of rated output

Automatic boost: automatically determine the boost torque according to the output current and combined with the motor parameters

Automatic      current limiting and pressure limiting

Whether during acceleration, deceleration or stable

operation, the motor stator current and voltage are

automatically  detected and  suppressed within  the

allowable range based on a unique algorithm to minimize

the possibility of system fault tripping.

Inductive vector

control

Voltage      frequency

characteristics

Automatically adjust the output voltage-to-frequency

ratio based on motor parameters and unique algorithm

Torque characteristics

Starting torque:

100% rated torque at 5.0Hz (VF control)

150% rated torque at 1.0Hz (vector control)

Current  and  voltage

suppression

Full current closed-loop control, completely avoiding

current  impact,  with  complete  overcurrent  and

overvoltage suppression functions

Undervoltage

suppression during

operation

Especially for users with low grid voltage and frequent fluctuations in grid

voltage, even if the voltage is lower than the allowed voltage range, the system

can maintain the longest possible operating time based on a unique algorithm and

residual energy allocation strategy.

Multi-speed
