EM542S Digital Stepper Drive User Manual 5.2 6-lead Motor Connection EM542S can power 6-lead stepper motors through half coil connection (half chopper) or full coil (full copper) connection. The half coil connection only uses one half of the motor’s windings and is usually selected in applications requiring high speed but lower torque. -

EM542S Digital Stepper Drive User Manual 11. Protection Functions EM542S incorporates are built with over-voltage and over-current error protections. When it is under error protection, the red LED light will blink for one or two times in a period of 3 seconds. If fault output connection is connected, the impedance mode between ALM+ and ALM- will be changed (See “Fault Output Configuration”... -
Page 17: Troubleshooting
EM542S 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. -
