12.5 Diagnostics and troubleshooting

This section provides diagnostics and troubleshooting information related to communication or
12
interference with the controller. For information about the servo drive alarms, refer to Chapter 14
Troubleshooting.
1. The SYNC communication cycle of the controller and servo drive is different
Since the jitter of each controller is different, the time the servo drive receives the SYNC
differs from the SYNC communication cycle time. When this happens, adjust the value of
P3.009.U to increase the error range and let the servo drive automatically correct the
internal timer so it is consistent with the communication cycle of the controller.
2. Eliminate 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.
