Channel %1 block %3 axis %2 at software limit switch %4
%1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
%4 = String
During the traversing motion, the system detected that the software limit switch would be
crossed in the direction indicated. During block preparation, it was not yet possible to
detect that the traversing range would be exceeded: Either there has been a motion over-
lay by the handwheel or a coordinate transformation is active.
- Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
- If the axis is a single axis when this alarm is triggered, the alarm is only effective for this
axis (not effective for e.g. the channel or mode group)
Depending on the reason for this alarm being triggered, the following remedial measures
should be undertaken:
• Handwheel override: Cancel the motion overlay and avoid this or keep it smaller when
the program is repeated.
• Transformation: Check the preset/programmed zero offsets (current frame). If the val-
ues are correct, the tool holder (fixture) must be moved in order to avoid triggering the
same alarm when the program is repeated, which would again cause the program to be
aborted.
Clear alarm with the RESET key. Restart part program
Channel %1 axis %2 rests on software limit switch %3
%1 = Channel number
%2 = Axis name, spindle number
%3 = String
The specified axis is already stationary at the displayed software limit.
- Alarm display.
Please inform the authorized personnel/service department. Machine data 36110
POS_LIMIT_PLUS/36130 POS_LIMIT_PLUS2 and 36100 POS_LIMIT_MINUS/36120
POS_LIMIT_MINUS2 must be checked for the software limit switches.
Shut down in JOG mode from the software limit switch.
Please inform the authorized personnel/service department.
Machine data:
Check the axis-specific interface signals: "2nd software limit switch plus" (DB 31 - 61,
DBX 12.3) or "2nd software limit switch minus" (DB 31 - 61, DBX 12.2) check whether the
2nd software limit switch is selected.
Alarm display showing cause of alarm disappears. No further operator action
Channel %1 block %2 axis %3 at working area limit %4
%1 = Channel number
%2 = Block number, label
%3 = Axis, spindle number
%4 = String ( + or - )
The specified axis violates the working area limitation. This is recognized only in the main
run either because the minimum axis values could not be measured before the transfor-
mation or because there is a motion overlay.
