Page 4: Introductions
1.2 Applications The DMA860E 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. -
Page 5: Environment
Side mounting recommended for better heat dissipation 2.4 Elimination of Heat DMA860E reliable working temperature should be < 60℃ (140°F) It is recommended to use automatic idle-current mode to reduce motor heating. That means set the SW4 pin of ... -

3. Connection Pin Assignments and LED Indication The DMA860E 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. -
Page 7: Led Light Indication
3.3 LED Light Indication There are two LED lights for DMA860E. The GREEN one is the power indicator which will be always on generally. The RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection enabled for a DMA860E. -

DMA860E Digital Stepper Drive User Manual Figure 4: 4-lead Motor Connections 5.2 Connections of 6-lead Motor Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operations. The higher speed configuration, or half coil, is described, because it uses one half of the motor’s inductor windings. -

6. Power Supply Selection The DMA860E can power medium and large size stepping 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 DMA860E 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 DMA860E 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
DMA860E Digital Stepper Drive User Manual 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. 9. Typical Connection A complete stepping system should include stepping motor, stepping drive, power supply and controller (pulse generator). -

Page 14: Troubleshooting
DMA860E 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. -
