10760 Channel %1 block %2 helical axis is not parallel to tool orientation

Parameters: %1 = channel number

%2 = block number, label

Definitions: With active tool radius compensation a helix is only permissible if the helix axis is parallel to the tool,

i.e. the circle plane and the compensation plane must be identical.

Reaction: 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-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10761 Channel %1 block %2 tool radius compensation for ellipse with more

than one revolution 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 unlimited 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.

Reaction: 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-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

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 number of empty blocks is limited.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: 1.Modify part program:

2.Check whether SBL2 has been selected. With SBL2, a block is generated from each part program

line which can lead to exceeding the maximum permissible number of empty blocks between two tra-

versing blocks.

Program Con-

tinuation:

Clear alarm with NC START or RESET key and continue the program.

10763 Channel %1 block %2 path component of the block in the compensation

plane becomes zero

Parameters: %1 = channel number

%2 = block number, label

Definitions: Due to the collision monitoring with active tool radius compensation, the path component of the block

in the compensation plane becomes zero. If the original block contains no motion information perpen-

dicular to the compensation plane, it means that this block is excluded.

Reaction: Alarm display.
