What it means
A40102 reports that an alarm has occurred at the drive object at the DRIVE-CLiQ socket X102. The message does not name the underlying condition itself: its message value carries the alarm value from r2124, interpreted as a decimal number, and this value identifies the first alarm that has occurred for this drive object.
Why it appears
- An alarm has been raised at the drive object at the DRIVE-CLiQ socket X102.
What to check
- Open the alarm buffer of the drive object specified in the message.
- Evaluate the entries: the alarm value in r2124, interpreted as a decimal number, identifies the first alarm that has occurred for this drive object.
Reading the message value
- The drive writes the alarm value into the message value, which the manual prints as the placeholder %1.
Alarm value (r2124, interpret decimal): First alarm that has occurred for this drive object.
Parameters the manual names
- r2124 — alarm value; for this alarm, read r2124 as a decimal number to see the first alarm that has occurred for the drive object at DRIVE-CLiQ socket X102.
Acknowledging and restarting
The alarm triggers no converter reaction and does not need to be acknowledged. There is no separate reset step for A40102 itself; the remedy is to evaluate the alarm buffer of the specified drive object and follow up the alarm found there.
