What it means
A40100 reports that an alarm has occurred at the drive object at the DRIVE-CLiQ socket X100. The alarm is a pointer: its message value identifies the alarm that actually occurred — it is the first alarm that has occurred for this drive object, taken from r2124 and interpreted as a decimal number. The drive takes no automatic reaction to this alarm, and no acknowledgment is required.
Why it appears
- An alarm has occurred at the drive object at the DRIVE-CLiQ socket X100.
What to check
- Evaluate the alarm buffer of the specified drive object — the object whose alarm is being reported for socket X100.
- Read the alarm value in r2124 and interpret it as a decimal number: it contains the first alarm that has occurred for this drive object, which tells you which alarm you are actually dealing with.
Reading the message value
- The message value holds the alarm value from r2124; the drive instructs you to interpret it as a decimal number.
- The value is the first alarm that has occurred for this drive object.
Parameters the manual names
- r2124 — alarm value: for this alarm, read r2124 and interpret the value as a decimal number to identify the first alarm that has occurred for the drive object at socket X100.
Acknowledging and restarting
No acknowledgment is required for this alarm. Because it only reports that another alarm has occurred at the drive object at DRIVE-CLiQ socket X100, the follow-up is the remedy itself: evaluate the alarm buffer of the specified object — the alarm recorded there is the one that actually needs attention.
