Overview of Alarms
Remedy: 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 values
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.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
10621
Channel %1 axis %2 rests on software limit switch %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = String
Definitions: The specified axis is already stationary at the displayed software limit.
Reactions: - Alarm display.
Remedy: 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: "2. "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.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
10630
Channel %1 block %2 axis %3 at working area limit %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis, spindle number
%4 = String ( + or - )
Definitions: 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.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Program other motion or do not perform overlaid motion.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
10631
Channel %1 axis %2 rests at working area limit %3
Parameters: %1 = Channel number
%2 = Axis, spindle
%3 = String ( + or - )
Definitions: The specified axis reaches the working area limitation in JOG mode.
Reactions: - Alarm display.
