12.5 Diagnostics and troubleshooting

This section provides diagnostics and troubleshooting information related to communication or

interference with the controller. For information about the servo drive alarms, refer to Chapter 13.

1. The SYNC communication cycle of the controller and servo drive is different

Since the jitter of each controller is different, the communication cycle time between the

servo drive receiving the Sync and Sync synchronization action is different. When this

happens, increase the error value (T) by adjusting P3.009 and let the servo drive

automatically correct the internal timer so it is consistent with the communication cycle of

the controller.

2. Clear interference

Packets are particularly sensitive to interference in high-speed network communication

applications. To achieve fast and high-precision control, the selection of the wire is

extremely important. Use shielded cables for the communication wiring, and make sure that

the cable shield is firmly connected to the servo drive communication port. Also, ensure the

ground wire is properly connected and grounded.
