Overview of Alarms
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Place selection of the CRC such that the starting point of the approach movements
comes to rest outside of the correction circle around the target point (programmed tra-
versing movements > compensation radius). The following possibilities are available:
• Selection in the previous block
• Insert intermediate block
• Select approach behavior NORM
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10756
Channel %1 block %2 deselection of the tool radius compensation via KONT not
possible at the programmed end point
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: On deselection of the cutter radius compensation, the programmed end point is within the
compensation circle. If this point were in fact to be approached without compensation,
there would be a contour violation.
If the cutter radius compensation is deselected via G40, the approach behavior (NORM or
KONT) determines the compensation movement if the programmed end point is behind
the contour. With KONT, a circle is drawn with the cutter radius about the last point at
which the compensation is still active. The tangent passing through the programmed end
position and not violating the contour is the retraction movement.
If the start point is within the compensation circle around the target point, no tangent
passes through this point.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Place deselection of the CRC such that the programmed end point comes to rest outside
the compensation circle around the last active compensation point. The following possibil-
ities are available:
• Deselection in the next block
• Insert intermediate block
• Select retract behavior NORM
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10757
Channel %1 block %2 changing the compensation plane while tool radius compen-
sation is active not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In order to change the compensation plane (G17, G18 or G19) it is first necessary to
deselect the cutter radius compensation with G40.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
