    Description

    The MA860H is a high performance microstepping driver based on pure-sinusoidal currentcontrol technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.

    Pin Details
    PUL+


    PUL-
    Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal; 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. For reliable response, pulse width should be longer than 1.5μs. Series connect resistors for current-limiting when+12V or +24V used. The same as DIR and ENA signals.
    DIR+


    DIR-
    DIR signal: In single-pulse mode, this signal has low/high voltage levels,representing two directions of motor rotation. For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH,0-0.5V when DIR-LOW. Please note that motion direction is also related tomotor-driver wiring match. Exchanging the connection of ?two wires for a coilto the driver will reverse motion direction.
    ENA+

    ENA-
    Enable signal: This signal is used for enabling/disabling the driver. High level(NPN control signal, PNP and Differential control signals are on the contrary,namely Low level for enabling.) for enabling the driver and low level fordisabling the driver. Usually left UNCONNECTED (ENABLED)

    Selecting Microstep Resolution and Drive Output Current


    This driver uses an 8-bit DIP switch to set microstep resolution, and motor operating current, as shown below:
