DM542T(V4.0) Digital Stepper Drive User Manual 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 15: Sequence chart of control signals Remark: t1: ENA must be ahead of DIR by at least 200ms. -
Page 11: Troubleshooting
DM542T(V4.0) 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.
