Ext I/O comm loss

What does 7082 mean?

The drive trips on this fault when communication to an I/O extension module fails. This is a critical communication failure that will halt drive operation, preventing proper control, command execution, and potentially causing significant process downtime.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Confirm that communication parameters, such as baud rate and addressing, are correctly configured in both the drive and the I/O module.

2. 4

   Inspect the I/O module for diagnostic LEDs indicating status or errors. If internal fault is suspected, consider replacing the module.
