Signal Terminal Content
ALM The motor or driver controls the fault signal output signal, which is normally 5V,
and the level is 0V when the fault occurs.
  SPEED Corresponding to the operating speed of the motor, the corresponding pulse frequency is output. With SPEED-OUT, the speed of the motor can be calculated.
The calculation formula is:
F:Output pulse frequency(HZ);P:Motor grade logarithm;N:Motor speed
For example: motor 4 pole
BRK When the BRK and COM terminals are disconnected or the high level is input,
the motor brake stops. When the motor is shorted or low level, the motor runs.
  EN When the EN terminal is disconnected from the COM terminal
or the high-level input is input, the motor stops slowly. When the short-circuit
or low-level input is used, the motor runs.
  F/R When the F/R terminal is short-circuited with the COM terminal or
the high-level input,the motor rotates forward, and when the short-circuit or
low-level input is used, the motor reverses.
  COM Public port (OV reference level)
  SV ①external speed potentiometer ②external analog signal input ③ pulse frequency input
  VCC External potentiometer interface
Hall signal REF+ DC brushless motor Hall signal power supply.
  HU DC brushless motor Hall signal HU.
  HV DC brushless motor Hall signal HV.
  HW DC brushless motor Hall signal HW.
  REF- The DC brushless motor Hall signal is grounded.
U DC brushless motor U phase.
  V DC brushless motor V phase.
  W DC brushless motor W phase.
DC- DC power input to the negative pole.
  DC+ The DC power input is positive. (Voltage range DC24V-DC52V)
