V / f curve type: straight line, multipoint, power function, V / f separation;

Torque boost support: Automatic torque boost (factory setting), manual torque boost

Support linear and S curve acceleration and deceleration;

4 groups of acceleration and deceleration time, setting range 0.00s ~ 60000s

Overvoltage stall control: limit the power generation of the motor by adjusting the output frequency to avoid skipping the voltage fault;

Undervoltage stall control: control the power consumption of the motor by adjusting the output frequency to avoid yaw failure

VdcMax Control: Limit the amount of power generated by the motor by adjusting the output frequency to avoid over-voltage trip;

VdcMin control: Control the power consumption of the motor by adjusting the output frequency, to avoid jump undervoltage fault

5% ~ 50.0%

For the amplitude of high-frequency signal injection, the larger the set value, the higher the accuracy of position identification, but the greater the noise of the motor. The set value should be as small as possible when the accuracy meets the requirements.

MTPA is the maximum torque current ratio control. Enabling MTPA can reduce the motor current when SVC and VC are running under load.
