    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: How to determine the DC supply power of stepper motor driver?
    A. Determination of voltage
    Supply voltage of hybrid stepper motor driver is generally a wide range (e.g.: the supply voltage of ATODSP42 is 18-40VDC). The power voltage is generally selected according to the working speed and response requirement. However, if the working speed and response requirement of motor is fast, the voltage value also should be high. However, the ripple wave of power voltage also cannot exceed maximum input voltage of driver, or driver may be destroyed.
    B. Determination of current
    The supply current is generally determined according to the output current I of the driver. If linear power is used, the power current is generally 1.1-1.3 times of I. If the switch power is used, the power current is generally 1.5-2.0 times of I.
