Overview of Alarms
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Orient helix axis perpendicular to the machining plane.
Program Con- Clear alarm with NC START or RESET key and continue the program.

Channel %1 block %2 tool radius compensation for ellipse with more than one rev-
olution not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When machining the inside of an ellipse, in parts of the ellipse the curvature radii are
greater than or smaller than the cutter radius compensation.
In ellipses, in this case the block would be split up into 4 subblocks with curvature radii
that are greater than and less than the compensation radius. Over several revolutions,
there would be a tremendous increase in the amount of calculation required by the unlim-
ited number of resulting subblocks, and therefore this situation is rejected by the error
message.
If compensation is possible everywhere or nowhere on the ellipse, then ellipses are also
permissible that cover more than one full revolution.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Use cutter with smaller radius or program motion block on blocks with no more than one
revolution.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10762
Channel %1 block %2 too many empty blocks between two traversing blocks with
active tool radius compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The maximum permissible number of empty blocks is limited by a machine data.
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
• Modify machine data
• Check whether SBL2 is activated. With SBL2, a block is generated from each part pro-
gram line which can lead to exceeding the maximum permissible number of empty blocks
between two traversing blocks.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10763
Channel %1 block %2 path component of the block in the compensation plane
becomes zero
