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%4
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = String
%4 = The axis of the software limit switch is only output if different from the traversing axis.
Definitions: The specified axis is already positioned at the displayed software end delimiter.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. Check machine data MD36110
$MA_POS_LIMIT_PLUS/MD36130 $MA_POS_LIMIT_PLUS2 and MD36100
$MA_POS_LIMIT_MINUS/MD36120 $MA_POS_LIMIT_MINUS2 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 whether the 2nd software limit switch has been selected in the.axis-specific interface signals:
"DB31, ... DBX12.3 (2nd software limit switch plus) and DB31, ... DBX12.2 (2nd software limit switch
minus).
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 transformation or because there
is a motion overlay.
Reaction: 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
