    Description

    The DM422 is a versatility fully digital stepping driver based on a DSP with advanced control algorithm. The DM422 is the next generation of digital stepping motor controls. It brings a unique level of system smoothness, providing optimum torque and nulls mid-range instability. Motor self-test and parameter auto-setup technology offers optimum responses with different motors and easy-to-use. The driven motors can run with much smaller noise, lower heating, smoother movement than most of the drivers in the markets. Its unique features make the DM422 an ideal solution for applications that require low-speed smoothness. What's more, a pulse filter has been built into the DM422.

    Connector P1 Configurations


    Pin Details
    PUL Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active both at high level and low level (software configurable). For reliable response, pulse width should be longer than 7.5µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.
    DIR DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (software configurable), this signal is counter-clockwise (CCW) pulse,active both at high level and low level (software configurable). 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 rotation direction is also related to motor-driver wiring match. Exchanging the connection of two wires for a coil to the driver will reverse motion direction.
    OPTO Opto-coupler power supply, and the typical voltage is +5V. Series connect resistors (at the PUL, DIR, ENA terminals) for current-limiting when +12V or +24V used.
    ENA Enable signal: This signal is used for enabling/disabling driver. High level for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED).

    Selecting Microstep Resolution and Drive Output Current


    Microstep resolutions and output current are programmable, the former can be set from full-step to 102,400 steps/rev and the latter can be set from 0.3A to 2.2A.
    However, when it's not in software configured mode, this driver uses a 6-bit DIP switch to set microstep resolution, and motor operating current, as shown below:

    Notes: Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly under high speed condition.

    Warning


    • Make sure the power supply voltage dose not exceed the drive’s input range. Double check the connections and make sure the power lead polarity is correct.
    • Do not set high current to small stepper motor. It is possible that the motor will be damaged.
    • Disconnect the motor from the load if you are not sure the move direction. Adjust the axis in the middle before trying to run the motor.
    • Never disconnect the motor lead when the power source is energized.
