    Function Description
    Functions Operation Instructions
    Signal Interface PUL PUL+ is the positive end of the control pulse signal PUL- is the negative end of the control pulse signal
    DIR DIR+ is the positive end of directional signal DIR- is the negative end of directional signal
    ENA ENA+ is the positive end of enabling signal ENA+ is the negative end of enabling signal
    Motor Interface A A+ is connected with the positive end of the A phase winding of the stepping motor A- is connected with the negative end of the A phase winding of the stepping motor
    B B+ is connected with the positive end of the B phase winding of the stepping motor B- is connected with the negative end of the B phase winding of the stepping motor
    When the A and B two phase windings are switched, the motor direction is reversed
    Indicator Light 1. The green light is the power indicating lamp. When the drive is powered on, the green light is always on. 2. The red light is the fault indicating lamp. When the overvoltage and overcurrent faults occur, the trouble lamp is always on.

    Tips: Low frequency characteristics of servo motor and stepper motor
    Stepper motors are prone to low-frequency vibration at low speed. Vibration frequency is connected with load conditions and drive performance. Meanwhile, it is generally considered to be half the motor's take-off frequency in no-load condition. This low-frequency vibration, which is determined by the working principle of the stepping motor, is very unfavorable for the normal operation of the machine. When the stepper motor works at low speed, damping technology (such as adding a damper on the motor, or the use of subdivision technology on the drive) should generally be used to overcome the phenomenon of low frequency vibration. The AC servo motor operates very smoothly and does not vibrate even at low speeds.
    AC servo system with resonance suppression function can cover the lack of mechanical rigidity, and the system has a frequency analysis function (FFT), which can detect the mechanical resonance point and is convenient for system adjustment.
