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 compen-

sation circle around the last active compensation point. The following possibilities are available:

Deselection in the next block

Insert intermediate block

Select retract behavior NORM

Program Con-

tinuation:

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

10757 [Channel %1: ] Block %2 changing the compensation plane while tool

radius compensation 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 cut-

ter radius compensation with G40.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Insert an intermediate block in the part program using the correction deselection. After the plane

change, the cutter radius compensation is to be selected in an approach block with linear interpolation.

Program Con-

tinuation:

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

10758 [Channel %1: ] Block %2 curvature radius with variable compensation

value too small

Parameters: %1 = Channel number

%2 = Block number, label

Definitions: The current cutter radius compensation (the cutter used) is too large for the programmed path radius.

In a block with variable tool radius compensation, a compensation must be possible either anywhere

or nowhere on the contour with the smallest and the largest compensation value from the programmed

range. There must be no point on the contour in which the curvature radius is within the variable com-

pensation range.

If the compensation value varies its sign within a block, both sides of the contour are checked, other-

wise only the compensation side.

Reaction: Correction block is reorganized.

Local alarm reaction.

Interface signals are set.

Alarm display.

NC Stop on alarm at block end.

Remedy: Use smaller cutters or allow for a part of the cutter radius at the time of contour programming.

Program Con-

tinuation:

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

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.
