Yaskawa · E7 Drive
An unrecognizable option board is connected to the control board, indicating a type mismatch or an unsupported option card. This prevents the drive from correctly interfacing with the option card, leading to functional limitations or failure.
Click steps to track your progress.
1. Power down the drive, remove the option card, and verify its part number against the drive's compatibility list in the manual.
2. Inspect the option card connector and the drive's slot for bent pins or debris; clean and re-seat the card firmly.
3. Check the drive's main control board firmware version and compare it with the option card's compatibility requirements.
4. Try a known-good, compatible option card to confirm the issue is with the existing card or the drive's slot.
5. If the card is confirmed incompatible, replace it with the correct model specified for the drive.
