1. Control port
5V — Driver board internal output voltage, for external potentiometer or switch for speed adjustment and reversing operation
Z/F —Rotating direction control ports. Connect “5V” high level or no connect is Forward direction, connect 0V 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%
EL —Enable port control. Connect 5V or no connect to enable operation, connect GND to disable operation.
Singnal—Speed pulse signal output
GND—Used for Driver board internal control
2. Power port
MA ----motor phase A
MB ---- motor phase B
MC---- motor phase C
P- ----DC-
P+----DC +
3: Hall sensor port
Ha--- Hall a
Hb--- Hall b
Hc--- Hall c
GND---GND
5V---5V input
4: Remarks
1. 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.
2. Control port distance: 2.54mm,Power port distance:3.96 mm
3. Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate.
