Block %2 Wab Distance Invalid Or Not Programmed; Block %2 Wab Programmed Several Times; Block %2 No Valid Wab Direction Defined - Siemens Sinamics S120 Diagnostic Manual

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.
Continuation:
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.
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:
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.
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.
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.
