Driver wiring port description




Indicator light


green power indicator light, power on, indicating that the power supply is normal


red status indicator, slow flashing, waiting. fast flashing, running, and it changes with the motor speed, indicator always on for failure or offline

RS232  Communication port


can be connected to an external speed display board to display the speed; it can also be connected to a computer to set drive parameters

Control signal terminal


Control signal power supply positive


External speed control signal, adjust the motor speed through an external potentiometer


Reserved function terminal


Motor speed pulse output, can be converted into the actual speed of the motor by measuring the frequency of this signal


control the motor forward and reverse, connect to GND1, the motor will reverse, when not connected to GND1 , the motor will rotate forward, when switching between forward and reverse, in order to reduce the impact, first set EN to stop the motor


Motor EN control, EN connects to GND1, the motor rotates, if EN is not connected to GND1, the motor does not rotate


Alarm output, when the circuit is in alarm state, output low level (OC gate output)


Control signal power ground

Hall signal terminal


Motor Hall power supply positive


Hall sensor signal U phase input


Hall sensor signal V phase input


Hall sensor signal W phase input


Motor Hall power ground

Motor and power terminal


Motor three-phase output signal, connected to motor winding


DC 24V~48V power supply input
