5V -----Driver board internal output voltage
M ---- Motor speed pulse signal output port, 5V pulse signal.
1. Control port
Z/F---- Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0 V low level or connect to GND is reverse direction.
VR ----Speed control port. Analog voltage linear speed regulation 0.1v -5V, The input resistance is 20K Ohm ,connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ; Duty cycle 0-100%
GND—Used for Drive board internal control
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
3. Use shielded wires if the drivers board has more than 50 cm distance from the motor, otherwise it may lead to abnormal driving, affecting the normal use.
4.Control port distance: 2.54mm,Power port distance:3.96 mm
5. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
