Support linear and S curve acceleration and deceleration;

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

DC bus voltage control

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

Carrier frequency

1kHz~ 12kHz(Varies depending on the type)

Startup method

Direct start (can be superimposed DC brake); speed tracking start

Stop method

Deceleration stop (can be superimposed DC braking); free to stop
