What it means
A40104 reports that an alarm has occurred at the drive object at the DRIVE-CLiQ socket X104. The alarm itself is only a pointer: the alarm value stored in r2124, read as a decimal number, contains the first alarm that has occurred for this drive object. The drive takes no automatic action in response to this alarm, and it does not have to be acknowledged.

What to check
