This fault indicates that the power structure requires a newer Application revision to be compatible with the main control board. The firmware on the power structure is outdated or incompatible, preventing correct drive operation. The drive will not function until the power board firmware is updated to the required version.
Click steps to track your progress.
1. Identify the current firmware versions of both the main control board (MCB) and the power board (PB) using programming software (e.g., DriveTools SP).
2. Obtain the correct, compatible firmware update file for the power board based on its model and the MCB's version.
3. Perform a firmware update on the power board (PB) using the approved flashing tool and procedure, ensuring no interruptions.
4. Verify that the MCB and PB are from compatible product series and generations as specified in the drive's documentation.
5. If the firmware update fails or the fault persists, replace the power board (PB).
