DM542E Full Digital Stepper Drive Manual V2.0 Full Coil Configurations The full coil configuration on a six lead motor should be used in applications where higher torque at lower speed is desired. This configuration is also referred to as full copper. In full coil mode, the motors should be run at only 70% of their rated current to prevent overheating.
6. Power Supply Selection The DM542E can match medium and small size stepping motors (frame size from NEMA17 to 34) made by Leadshine or other motor manufactures around the world. To achieve good driving performances, it is important to select supply voltage and output current properly.

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 10: Sequence chart of control signals Remark: t1: ENA must be ahead of DIR by at least 5s.
DM542E Full Digital Stepper Drive Manual V2.0 12. Frequently Asked Questions 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.
