Port Description
1.Control Port (Left)
GND — Used for Driver board internal control
VR — Speed control port. Analog voltage speed regulation 0.1V-5V speed regulation, linear speed regulation from low to high. PWM speed regulation needs to be grounded with the driver board.
Z/F — Rotating direction control ports.Connect 5V high level or no connect in one direction, connect 0V low level or GND to the other direction.
FG — Motor speed pulse signal output port, 5V pulse signal
5V — Driver board internal output voltage, external potentiometer or switch for speed adjustment and reversing operation.
2. Power Port(Right)
P+ — DC +
P- — DC -
MC — Motor Phase C
MB — Motor Phase B
MA — Motor Phase A
3. Please pay attention to the motor phase wire and Hall wire not to be too long, because the driver board relies on back electromotive force detection, it will cause signal interference If the wire is too long.
4. The port distance is 2.54mm for both Power port and Control Port.
5. When adding heat sink or placing the driver board, please pay attention to the insulation for the driver board.
