           Name

    Function

    PUL

    Pulse input signal

    DIR

    Direction input signal, used to change the direction of motor operation, in order to ensure reliable reversing motor, the direction of the signal should be
    The initial direction of operation of the motor is related to the wiring of the motor windings, and the interchange of any phase winding (eg A +, A-exchange) can change the direction of the initial operation of the motor

    OPTO

    Pulse / direction / enable signal power positive side, the default external 5V, such as the use of +12 V or +24 V need to connect in series resistance

    ENA

    Enables the control signal, which is used to enable or disable the drive output. When the ENA is low (or internal optocoupler), the driver will cut off the current of each phase of the motor so that the motor is in a free state and does not respond to stepping pulses. When this function is not required, use the signal side to float

    Static current setting 
    The quiescent current can be set with the SW4 DIP switch, off that the quiescent current is set to half the operating current, and on is the same as the operating current. SW4 should be set to off for general use, which reduces the heat generation of the motor and the drive, reduces the energy consumption and improves the reliability. Pulse signal to stop 0.4 seconds after the current automatically halved, heat theoretically reduced to 25%.
