    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: Subdivision control of stepper motor
    Stepper motor subdivision control is precisely controlled by the driver of stepper motor phase current. The two-phase motor, for example, if the rated current of motor is 3A, if you are using a conventional drive (such as a common mode of constant current chopper) driving the motor, every step motor running, in its winding current will mutations from 0 to 3A or 3A mutation to 0, the great changes in phase current, is bound to cause vibration and noise of motor running. If using subdivision driver, under the conditions of 10 subdivision drive the motor, step motor each runs a micro, current changes in the winding is only 0.3A, rather than 3A, and the law of electric current is a sine curve changes, thus greatly improves the motor vibration and noise, therefore, on the performance of advantages is the real advantages of segmentation. Due to the precise control of the phase current of the motor, the drive should have high technical requirements and technical requirements.
