Overview of Alarms
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.
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:
10745
Channel %1 block %2 WAB end position not clear
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In the WAB block and in the following block, the position has been programmed perpen-
dicular to the machining direction. In the WAB block, no position has been indicated in the
machining plane.
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. Either remove the position data for the infeed axis from the WAB
block or the following block, or program a position in the machining plane in the WAB
block as well.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10746
Channel %1 block %2 block search stop for WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A block search stop has been inserted between a WAB approach block and the following
block defining the tangent direction or between a WAB approach block and the following
block defining the end position.
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:
10747
Channel %1 block %2 retraction direction not defined for WAB
Parameters: %1 = Channel number
%2 = Block number, label
