10746 [Channel %1: ] Block %2 block search stop for WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A preprocessing stop has been inserted between an SAR approach block and the following block
defining the tangent direction or between an SAR retraction block and the following block defining the
end position.
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10747 [Channel %1: ] Block %2 retraction direction not defined for WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a WAB retraction block with quarter circle or semi-circle (G248 or G348), the end point in the
machining plane was not programmed, and either G143 or G140 without tool radius compensation is
active.
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. The following changes are possible:
- Indicate end point in the machining plane in the WAB block.
- Activate tool radius compensation (effective for G140 only, not for G143).
- State retraction side explicitly with G141 or G142.
- Perform retraction with a straight line instead of a circle.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10748 [Channel %1: ] Block %2 illegal retract plane with WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: By means of DISRP a position of the retraction plane has been programmed which is not situated
between the safety distance (DISCL) and the starting point (during approach) and/or end point (during
retraction) of the WAB movement.
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10750 [Channel %1: ] Block %2 tool radius compensation activated without tool
number
Parameters: %1 = Channel number
%2 = Block number, label
