    1.2 Applications The DM860E stepper drive are designed to power 2 phase (1.8°) or 4-phase (0.9°) NEMA 23, 24, 34, and 42 hybrid stepper motors. It can be easily adopted in many industries (CNC, medical, automation, packaging…), such as X-Y tables, engraving machines, labeling machines, mills, plasma, laser cutters, pick and place devices, and so on.

    3. Connection Pin Assignments and LED Indication The DM860E has two connector blocks P1&P2 (see above picture). P1 is for control signals connections, and P2 is for power and motor connections. The following tables are brief descriptions of the two connectors. More detailed descriptions of the pins and related issues are presented in section 4, 5, 9.

    3.4 Internal Jumpers CN6 & CN7 There are two jumpers CN6 and CN7 inside the DM860E. The CN6 is for control type selection and the CN7 is for turning on/off internal-microstep. Internal-microstep is mainly used to reduce motor vibration, when the customer uses microstep 400 - 1600.

    6. Power Supply Selection The DM860E can power medium and large size stepper motors (frame size from NEMA 23 to 42) made by Leadshine or other motor manufacturers. To get good driving performances, it is important to select supply voltage and output current properly.

  • Page 10: Power Supply Sharing

    6.2 Power Supply Sharing Multiple DM860E drives can share one power supply to reduce cost, if that power supply has enough power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately. To avoid cross interference, DO NOT daisy-chain connect the power supply input pins of the Drivers.

    The current automatically reduced to 50% of the selected dynamic current 0.4 second after the last pulse. 7.3 Automatic Motor Matching & Self Configuration When powered on a DM860E will automatically configure itself with the best settings to match the driven stepper motor for optimal performance. No action is needed.

  • Page 12: Typical Connection

    DM860E Digital Stepper Drive User Manual recommended instead of daisy-chaining.  It is prohibited to pull and plug connector P2 while the drive is powered ON, because there is high current flowing through motor coils (even when motor is at standstill). Pulling or plugging connector P2 with power on will cause extremely high back-EMF voltage surge, which may damage the drive.

    DM860E Digital Stepper Drive User Manual 12. Troubleshooting In the event that your drive doesn’t operate properly, the first step is to identify whether the problem is electrical or mechanical in nature. The next step is to isolate the system component that is causing the problem. As part of this process you may have to disconnect the individual components that make up your system and verify that they operate independently.
