Definitions: Selection of cutter radius compensation with G41/G42 may only be performed in blocks
where the G function G00 (rapid traverse) or G01 (feed) is active.
In the block with G41/G42, at least one axis in the plane G17 to G19 must be written. It is
always advisable to write both axes because, as a rule, both axes are traversed when
selecting the compensation.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Correct the NC program and put the compensation selection in a block with linear interpo-
lation.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:

Channel %1 block %2 deselection of the tool radius compensation only possible in
linear block
Parameters: %1 = Channel number

Channel %1 block %2 selection of the tool radius compensation via KONT not pos-
sible at the current starting point
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When activating the cutter radius compensation with KONT the starting point of the
approach block is within the compensation circle and therefore already violates the con-
tour.
If the cutter radius compensation is selected with G41/G42, the approach behavior
(NORM or KONT) determines the compensation movement if the present actual position
is behind the contour. With KONT, a circle is drawn with the cutter radius around the pro-
grammed initial point (= end point of the approach block). The tangent that passes
through the current actual position and does not violate the contour is the approach move-
ment.
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.
