Four speed regulation modes

Build-in potentiometer RV

Rotate the RV knob clockwise, the motor starts to run and accelerate.  Motor speed will decrease if anticlockwise.

When it gets to a limited position, the motor stops.

Peaking current setting

Equipped with a motor protection function, the driver provides options to set desired current number in the P-sv ,knob to avoid over-current for motor. Please note that the random error is ±10% . The setting should be matched with motor rated current.
