Option Board Code Number Fault
Yaskawa · F7 Drive
What does CPF22 mean?
An unrecognizable option board was connected to the control board, indicating an incompatible or incorrectly installed option board. The Drive cannot identify or communicate with the attached board, leading to system errors.
Common Causes
- Installation of an option board that is not compatible with the specific Drive model or firmware version.
- Option board not fully seated or incorrectly aligned in its expansion slot on the control board.
- Damaged pins or connectors on either the option board or the Drive's control board slot.
- Mismatched regional versions of the option board (e.g., requiring different voltage inputs) leading to recognition failure.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Power down the Drive completely, then verify the option board is correctly seated and fully engaged in its dedicated slot.
- 2
Check the Drive's hardware manual and the option board's part number to confirm compatibility with the specific Drive model (e.g., GA500, GA800).
- 3
Inspect the option board's connector pins and the Drive's slot for any signs of physical damage, bending, or debris.
- 4
If multiple option slots exist, attempt to install the board in an alternative compatible slot to rule out a slot issue.
- 5
Verify the Drive's main firmware version is up-to-date, as newer firmware often includes support for a wider range of option boards.
