The A5014 code on your ABB ACS310 drive indicates a panel control disabled issue. This means that even though the drive is receiving power and might be functioning internally, the control panel cannot be used to operate the drive.

There are two main reasons why this might happen:

1. Drive Faulted: If the drive has encountered a fault condition (identified by a separate fault code), the control panel might be disabled as a safety measure to prevent unintended operation.
2. Local Control Mode Lock: The drive might have a setting enabled that locks out control panel operation. This could be intentional for safety reasons during maintenance or a configuration issue.
