Remedy: Please inform the authorized personnel/service department.
Reduce the size of the buffer that has been assigned by modifying the NC program.
- By avoiding:
- Blocks without traversing information in the compensation plane
- Blocks with contour elements having a variable curvature (e.g. ellipses) and with curvature radii that
are smaller than the compensation radius. (Such blocks are divided up into several subblocks).
- Reduce the number of reviewed blocks for collision monitoring (MD20240
$MC_CUTCOM_MAXNUM_CHECK_BLOCKS).
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10753 [Channel %1: ] Block %2 selection of the tool radius compensation only
possible in linear block
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Selection of tool 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 advis-
able to write both axes because, as a rule, both axes are traversed when selecting the compensation.
Reaction: 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 interpolation.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10754 [Channel %1: ] Block %2 deselection of the tool radius compensation
only possible in linear block
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Deselection of tool radius compensation with G40 can only be performed in blocks where the G func-
tion G00 (rapid traverse) or G01 (feed) is active.
In the block with G40, 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 deselecting the compensation.
Reaction: 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 interpolation.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10755 [Channel %1: ] Block %2 selection of the tool radius compensation via
KONT not possible 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 contour.
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 programmed 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 movement.
If the start point is within the compensation circle around the target point, no tangent passes through
this point.
