Block %3 Axis %2 At Software Limit Switch %4; Axis %2 Rests On Software Limit Switch %3%4; Block %2 Axis %3 At Working Area Limit %4 - Siemens Sinamics S120 Diagnostic Manual

Program Clear alarm with the RESET key. Restart part program
Continuation:
10620 [Channel %1: ] Block %3 axis %2 at software limit switch %4
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
%4 = String
Definitions: During the traversing motion, the system detected that the software limit switch would be traversed in the direction
indicated. Exceeding the traversing range was not detected during block preparation because there has either been
a motion overlay or a zero offset has been executed or a coordinate transformation is active.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
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 Clear alarm with the RESET key. Restart part program
Continuation:
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: "DB380x
DBX1000.3 (2nd software limit switch plus) and DB380x DBX1000.2 (2nd software limit switch minus).
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
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 min-
imum axis values could not be measured before the transformation or because there is a motion overlay.
