NEMA17 BLDC Motor Driver
Four modes of speed regulation 
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.
POT Control
External potentiometer
Use a suitable potentiometer with a resistance value of 10KΩ, connect the middle terminal with SV terminal, and the other two terminals are respectively connected with VCC terminal and DC- terminal.

Input analog signal (0-5V)

Voltage Speed Control

Quick brake
BRK and COM are connected in default, the motor will be a quick brake, When BRK and COM are disconnected, the motor will rotate.
BRK control
CW/CCW rotation
Connect F/R and COM, the motor will rotate clockwise, disconnect it, the motor will rotate anticlockwise.
CW CCW Control
Peaking current setting
Equipped with a motor protection function, the driver provides options to set the desired current number in the P-sv , knob to avoid over-current for the motor. Please note that the random error is ±10% . The setting should be matched with motor rated current.
