I/O Board Fail

What does F122 mean?

A failure has been detected within the drive's control and I/O (Input/Output) section. This indicates a problem with the circuitry responsible for processing digital and analog inputs/outputs, and internal communication, which affects the drive's ability to interact with external devices and potentially its core control.

Complete Troubleshooting Guide

1. 1

   Cycle power to the drive to attempt a reset of the I/O board and associated systems.

2. 2

   Check all external wiring connected to the drive's I/O terminals for any short circuits or improper connections that could stress the I/O board.

3. 3

   If the fault cannot be cleared after cycling power and checking external wiring, replace the drive or the control module, as the I/O board is an integral component within these assemblies.
