ABB · Application Error ABB Motion Drives Error trouble shoo
The drive displays a boot error code (starting with 'b' on the seven-segment display) indicating a fatal error during the boot-up process. This generally points to issues with the memory module, firmware, or connected external hardware.
Click steps to track your progress.
Power down the drive, then remove and re-seat the memory module, ensuring it is correctly fitted.
Disconnect all connections apart from the logic supply power source.
Specifically, remove the encoder connection, as a damaged encoder can drag the control board voltage down.
Power up the drive again after performing the above steps.
If the problem persists, replace the memory module. If still unresolved, replace the drive unit.
