Modify part program.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 WAB distance invalid or not programmed
%1 = Channel number
%2 = Block number, label
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.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Modify part program.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 WAB programmed several times
%1 = Channel number
%2 = Block number, label
An attempt has been made to activate a WAB motion before a previously activated WAB
motion was terminated.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Modify part program.
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 no valid WAB direction defined
%1 = Channel number
%2 = Block number, label
The tangent direction for smooth approach or retraction is not defined.
Possible causes:
• In the program, no block with travel information follows the approach block.
• Before a retraction block, no block with travel information has been programmed in a
program.
• The tangent to be used for WAB motion is vertical to the current machining plane.
- Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
