Communication Error

What does CE mean?

This fault occurs due to electrical interference causing communication data errors within the control circuit, impacting reliable drive control. The drive detects this error if it fails to receive control data correctly within the detection time set by H5-09. Unresolved communication errors can lead to unpredictable drive behavior and system instability.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Separate communication wiring from drive power lines, and install a noise filter to the input side of the power supply specifically used for communication.

2. 4

   Address any sources of electrical interference originating from the controller itself, and then perform a Fault Reset to clear the error.
