What does COF mean?

This fault indicates a detected communication error on the CANopen communication card. This can be caused by wiring issues, incorrect CANopen node settings, or problems with the CANopen master device. Without resolving this, the drive will lose its CANopen network control capabilities, halting automated operation and remote diagnostics.

Complete Troubleshooting Guide

1. 1

   Check the CANopen communication bus connections, including cable integrity and proper termination resistors at both ends of the bus.

2. 2

   Verify the CANopen node ID, baud rate, and other network configuration parameters in the drive and compare them with the CANopen master settings.

3. 3

   Refer to the CANopen option card documentation for further specific diagnostics and troubleshooting procedures.
