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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

   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.
