    Description

    The DM542 is a fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared with traditional analog drives, DM542 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its unique features make DM542 an ideal choice for high requirement applications.
     

    Key Features


    • Anti-Resonance provides optimal torque and nulls mid-range instability
    • Motor auto-identification and parameter auto-configuration technology, offers optimal responses with different motors
    • Multi-Stepping allows a low resolution step input to produce a higher microstep output, thus offers smoother motor movement
    • 15 selectable microstep resolutions including 400, 800, 1600, 3200, 6400, 12800, 25600, 1000, 2000, 4000, 5000, 8000, 10000, 20000, 25000
    • Soft-start with no "jump" when powered on
    • Input voltage 18-50VDC
    • 8 selectable peak current including 1.00A, 1.46A, 1.91A, 2.37A, 2.84A, 3.31A, 3.76A, 4.20A
    • Pulse input frequency up to 200 KHz, TTL compatible and optically isolated input
    • Automatic idle-current reduction
    • Suitable for 2-phase and 4-phase motors
    • Support PUL/DIR and CW/CCW modes
    • Over-voltage, over-current protections

    Connector P1 Configurations


    Pin Details
    PUL+


    PUL-
    Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each
    rising or falling edge active (set by inside jumper J3); 5-24V when PUL-HIGH, 0-0.5V when
    PUL-LOW. In CCW mode (set by inside jumper J1), this input represents clockwise (CW)
    pulse. For reliable response, pulse width should be longer than 2.5μs.
    DIR+


    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-drive wiring match. Exchanging the connection of two wires for a coil to the drive will reverse motion direction.
    ENA+

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