Overview of Alarms
NCK alarms
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 cutter radius compensation with G40 can only be performed in blocks where the G
function 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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
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.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Place selection of the CRC such that the starting point of the approach movements comes to rest
outside of the correction circle around the target point (programmed traversing movements >
compensation radius). The following possibilities are available:
- Selection in the previous block
- Insert intermediate block
- Select approach behavior NORM
Program Clear alarm with NC START or RESET key and continue the program.
