What it means
A40105 reports that an alarm has occurred at the drive object connected at DRIVE-CLiQ socket X105. The alarm carries no diagnosis of its own: its message value points to the first alarm that has occurred for this drive object, stored as the alarm value in r2124. The drive takes no action because of this alarm and no acknowledgment is required — identifying and clearing the alarm recorded in r2124 is the actual task. The G130/G150 and S120/S150 manuals describe this alarm identically, so the same procedure applies on every family.
Why it appears
- An alarm was raised at the drive object connected to DRIVE-CLiQ socket X105.
What to check
- Evaluate the alarm buffer of the specified drive object — this is the remedy the manual gives for the alarm.
- Read the alarm value in r2124 and interpret it as a decimal number: it names the first alarm that has occurred for this drive object.
- Follow the entry for that alarm to find and clear the underlying condition.
Reading the message value
- The message value is the alarm value, read from r2124; the manual instructs to interpret it as a decimal number.
- Interpreted this way, the value is the first alarm that has occurred for this drive object. No further decoding of the value is given.
Parameters the manual names
- r2124 — alarm value: for this alarm, read it as a decimal number; it identifies the first alarm that has occurred for the drive object at socket X105.
Acknowledging and restarting
