1. Control port (right) 2.54 hole spacing
   
  5V-control board internal output 5V.
  EL - brake control port, reactive linear brake, with energy recovery function, analog voltage brake 0-5V. In the case of constant speed +, the higher the brake voltage, the greater the braking force 0-100%.
  M-Speed signal output port, pulse frequency is proportional to motor speed (pulse ratio is related to motor)
  Z / F-Positive and reverse control port. Hard change, 5V or suspended to one direction,GND to the other direction.
  VR - speed control port, analog voltage speed regulation 0V-5V(0-2.5V) speed regulation, linear speed regulation from low to high. External PWM speed regulation needs to be shared with the drive board.
  GND - control board.
   
   
  2. Power port (left) 3.96 hole spacing
  P + -Power input cathode 12V-48V (support lithium)
  P- -Power supply input negative electrode
  MC / W- -One of the motor phase line
  MB / V- -One of the motor phase line
  MA / U- -One of the motor phase line
  GND - -Motor Hall negative electrode
  HA-motor Hall signal one
  HB- -motor Hall signal one
  HC- -Motor Hall signal is one
  5V- -Motor Hall positive pole
   
  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. Pay attention to the heat dissipation if continue working with the max. Current.
