    ◆Current loop design, high torque at low speed, smooth operation

    ◆High torque high speed output, the maximum speed reaches 10000rpm/min(depend on speed of motor)

    ◆Speed control: 0-5V analog , PWM(10Hz-500Hz)

    ◆With signal input terminals EN (start/stop), DIR (direction)

    ◆With protection function of over current, over voltage, under voltage and motor block


    This product can achieve the following functions

    ◆Speed open loop operation with hall sensor

    ◆Speed close loop operation with hall sensor

    ◆Speed open loop operation without hall sensor

    ◆Speed close loop operation without hall sensor

    The above functions can be set directly on the drive panel.(Hall or without hall can be identified automatically)

    Instructions for the terminal

    Function  Mark  Description
     Control +5V power supply positive(Built-in power output)
    VSP External speed control signal, 0-100% of the motor speed adjustment through external potentiometer to change VSP voltage, 0~5V
    FG Motor speed pulse output, motor actual speed can be converted by measuring the frequency of this signal
    DIR Motor CW/ CCW rotation control ,CCW when connect DIR to GND,CW when not connect DIR to GND
    EN Motor enable control, EN is connected to GND, allowing the drive to run; EN is not connected,prohibiting the drive from running.
    GND Control signal power ground
    Hall +5V  Hall power supply positive
    HA  Hall sensor signal A phase input
    HB  Hall sensor signal B phase input
    HC  Hall sensor signal C phase input
    GND  HALL power ground
    Motor and power U、V、W motor three-phase output signals
    GND、V+  DC10V~50V power supply input


    Speed control mode (VSP) 1. Connect with external potentiometer to adjust speed: connect the two fixed ends of the external potentiometer (5K~10K) to the GND and +5V terminals of the driver respectively. By connecting regulating terminal to the VSP terminal. The speed can be controlled by external potentiometer, or inputting analog voltage to VSP terminal through other control units (such as PLC, MCU, etc.). The voltage range of the VSP port is DC 0V~+ 5V, corresponding to the speed of motor from 0 to max speed.
    2. Input PWM signal to adjust speed: connect PWM signal positive terminal to VSP terminal and negative terminal to GND. By setting the +5V PWM signal with the frequency of 10Hz-500Hz, through PWM duty cycle change to achieve speed adjustment.
    Speed signal output(FG)


    The drive provides speed pulse signal of motor which is proportional to motor speed.

    Speed calculation method: motor speed (RPM) = F÷N×60

    F = Actual frequency measured on the FG pin with the frequency meter

    N = motor poles pair (2 pairs pole motor N=2; 4 pairs pole motor N=4)

    For example, if the user selects a 4pairs poles motor, when the output FG signal is 200 Hz, motor speed = 200 ÷ 4 × 60 = 3000 rpm.


    CW/ CCW rotation


    By controlling the high and low level transitions of DIR terminal to control rotation of the motor.

    Note: In order to avoid huge impact to motor and mechanical equipment when motor changes direction suddenly at high speed, the drive decelerate the motor until it stops when DIR terminal receives commutation signal, then the motor changes direction and accelerates to the set speed.




    By controlling the high and low level transitions of EN terminal to control RUN/STOP of the motor. Motor runs normally when EN is in low level and stops when in high. When the start/stop is used to control the motor to stop, the motor stops naturally. Its motion law is related to load inertia. Factory setting is EN for allowed operation.
