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.
Reactions: - 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:
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 inter-
nally generated - WAB contour is negative. The internally generated WAB contour is a cir-
cle 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.
Reactions: - 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:
10743
Channel %1 block %2 WAB programmed several times
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: An attempt has been made to activate a WAB motion before a previously activated WAB
motion was terminated.
Reactions: - 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:
10744
Channel %1 block %2 no valid WAB direction defined
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The tangent direction for smooth approach or retraction is not defined.
