EN Comm Loss

What does F083 mean?

Internal communications between the drive's main controller and its embedded EtherNet/IP adapter have been interrupted. This is a fault internal to the drive's architecture, distinct from external network issues, signifying a failure in the communication path that prevents the drive from interacting with the Ethernet network. The drive's response is governed by parameter C125 [Comm Loss Action].

Complete Troubleshooting Guide

1. 1

   Cycle power to the drive to attempt re-establishment of internal Ethernet communication.

2. 2

   Check the EtherNet/IP setting parameters within the drive itself for correct configuration and integrity.

3. 3

   Review the drive’s internal Ethernet diagnostic parameters for specific error indicators.

4. 4

   Consider modifying parameter C125 [Comm Loss Action] to adjust the drive's behavior upon internal communication loss (e.g., coast, ramp to stop, continue last command).

5. 5

   If the fault persists, replace the Ethernet wiring (internal connections if accessible), the Ethernet switch (if connected directly), or the control module.
