20-74VDC, considering voltage fluctuation and EMF voltage. 3.4 P4 - Tuning Port 3DM883 has a tuning port with RS232 to modify the drive parameters, it’s only for tuning, not for equipment control because neither precision nor stability is sufficient. The interface definition is as follows: Figure 3 Tuning Port 3.5 Status LED (Protection Functions) -
Page 8: Control Signal And Fault Output Wiring
When over voltage or over current protection happens, 3DM883 red status LED light will blink and the impedance state between ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus be detected. Fault output connection is optional, and it can be connected either in sinking or sourcing. -

SW10. Setting to ON to activate the feature with 12ms acceleration time. 5.5 Automatic Motor Matching & Self Configuration When powered on a 3DM883 will automatically configure itself with the best settings to match the driven stepper motor for optimal performance. No action is needed. 6. Power Supply Selection The 3DM883 can power small and medium size 3-phase stepper motors (frame size from NEMA23 to 34) from Leadshine or other motor manufacturers. -

7. Motor Selection The 3DM883 can be used to drive 3- or 6-wire three-phase hybrid stepper motors with a step angle of 1.2 degrees. The choice of motor is mainly determined by the motor torque and current rating. The torque size is mainly determined by the size of the motor. -
Page 14: Troubleshooting
3DM883 3-Phase Digital Stepper Drive User Manual 8. 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. -
