The A5015 code on your ABB ACS310 drive indicates that the panel control is disabled because the local control mode lock is active. In simpler terms, the drive is receiving power and might be functioning internally, but the control panel cannot be used to operate it due to a specific setting.

• This alarm comes when panel control is disabled because the local control mode lock is active.
• Deactivate the local control mode lock and retry. See parameter 1606 LOCAL LOCK.
