10740 Channel %1 block %2 too many empty blocks in WAB programming
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: It is not allowed to program more blocks than specified by machine data
MC_WAB_MAXNUM_DUMMY_BLOCKS between the WAB block and the block determining the
approach and retraction tangent.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10741 Channel %1 block %2 direction reversal with WAB infeed motion
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A safety distance which has been programmed is located perpendicular to the machining plane and
not between the start and end point of the WAB contour.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10742 Channel %1 block %2 WAB distance invalid or not programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Possible causes:
- In a WAB block, the parameter DISR has not been specified or its value is less than or equal to 0.
- During approach or retraction with circle and active tool radius, the radius of the internally generated
- WAB contour is negative. The internally generated WAB contour is a circle with a radius which, when
offset with the current offset radius (sum of tool radius and offset value OFFN), yields the tool center
point path with the programmed radius DISR.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
