Option Board Failure

What does Option mean?

This fault indicates a failure or malfunction on an installed built-in option board within the VSD. This could be due to a hardware defect, incorrect installation, or corrupted firmware on the option board. Depending on the option board's function (e.g., fieldbus communication, I/O expansion), this can affect drive control, communication, or specific application functionalities. Continued operation with a failed option board might lead to unstable system behavior or loss of critical functions.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Try to re-initialize or reset the option board through the VSD's menu if such an option is available.

2. 4

   If the issue persists, consider replacing the option board with a new or known-good unit.

3. 5

   Contact service if troubleshooting does not resolve the issue, as firmware or deeper hardware diagnostics may be required.
