Overview of Alarms
Remedy: If no obvious operator error occurred: check the input value of the MD, check SGEs: was
the correct safe velocity selected? If the MDs and SGEs are o.k., check the machine for
any damage and rectify it.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27012
Axis %1 safe end position exceeded
Parameters: %1 = Axis number
Definitions: The axis has exceeded the limit position entered in MD $MA_SAFE_POS_LIMT_PLUS or
MD $MA_SAFE_POS_LIMIT_MINUS.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Stop the axis with STOP C,D or E, depending on the configuration in MD
$MA_SAFE_POS_STOP_MODE.
Remedy: If no obvious operator error occurred: Check the input value of the machine data and
check the SGEs: was the correct one of 2 limit positions selected? If the MDs and SGEs
are o.k., check the machine for any damage and rectify it.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
Remove the user agreement for this axis. Then press the RESET key causing the pro-
gram to be aborted and the alarm to be deleted. Traverse the axis in JOG mode to the
valid traversing range. After fault correction of the NC program and an axis position
check, the user agreement can be set again and the program can be restarted.
27013
Axis %1 safe braking ramp exceeded
Parameters: %1 = Axis number
Definitions: After the initiation of STOP B or C, the velocity exceeded the tolerance value entered in
MD $MA_SAFE_STOP_VELO_TOL.
Reactions: - Mode group not ready.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Channel not ready.
Pulse interlock by triggering a STOP A.
Remedy: Check MD $MA_SAFE_STOP_VELO_TOL. Check the braking behavior of the affected
drive.
Program Con- Switch control OFF - ON.
tinuation:
27020
Axis %1 stop E triggered
Parameters: %1 = Axis number
Definitions: This alarm is output together with alarms 27011 "Safe velocity exceeded" or 27012 "Safe
limit position exceeded" (when configured as such in MD
$MA_SAFE_VELO_STOP_REACTION or MD: $MA_SAFE_POS_STOP_MODE).
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
