1.2 Applications The DM882S 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.
Side mounting recommended for better heat dissipation 2.4 Elimination of Heat DM882S 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 DM882S 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.
3.3 LED Light Indication There are two LED lights for DM882S. 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 DM882S.

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. The higher torque configuration, or full coil, uses the full coil windings.
6. Power Supply Selection The DM882S can power medium and large size stepping motors (frame size from NEMA 34 and 42) made by Leadshine or other motor manufacturers. To get good driving performances, it is important to select supply voltage and output current properly.
6.3 Selecting Supply Voltage The DM882S is designed to operate within20-80VDC voltage input. When selecting a power supply, besides voltage from the power supply power line voltage fluctuation and back EMF voltage generated during motor deceleration needs also to be taken into account. Please make sure leaving enough room for power line voltage fluctuation and back-EMF voltage charge back.
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 DM882S will automatically configure itself with the best settings to match the driven stepper motor for optimal performance. No action is needed.
It is better to separate them by at least 10 cm, otherwise the disturbing signals generated by motor will easily disturb pulse direction signals, causing motor position error, system instability and other failures. If only one power supply serves multiple DM882S drives, separately connecting the drives to the power supply is ...
DMA882S Digital Stepper Drive User Manual Figure 10: Typical connection 10. Sequence Chart of Control Signals In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following diagram: Figure 11: Sequence chart of control signals Remark: t1: ENA must be ahead of DIR by at least 500ms.
DMA882S Digital Stepper Drive User Manual 11. Protection Functions To improve reliability, the drive incorporates some built-in protections features. Time(s) of Priority Sequence wave of red LED Description Blink Over-current protection activated when peak current exceeds the limit. Over-voltage protection activated when drive working voltage is greater than 113VDC Reserved.
DMA882S 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.
