Overview of Alarms
NCK alarms
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.
Reaction: 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 program 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 monitoring for acceleration 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.
Reaction: 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_MODE,
$MA_SAFE_VELO_STOP_REACTION or MD: $MA_SAFE_POS_STOP_MODE).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Trigger a LIFTFAST ASUB and internal activation of the safe operational stop (SBH) after expiry of
the time set in MD $MA_SAFE_STOP_SWITCH_TIME_E.
Remedy: Eliminate causes of the alarms "Safe velocity exceeded" or "Safe limit position exceeded" (see
description of these alarms).
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27021 Axis %1 stop D 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 $MA_SAFE_VELO_STOP_MODE,
$MA_SAFE_VELO_STOP_REACTION or $MA_SAFE_POS_STOP_MODE).
