Overview of Alarms
NCK alarms
10775 Channel %1 illegal tool change with face cutting in block %2
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm occurs when a tool change has been programmed while 3D tool radius compensation is
active with the result that the tool type changes or, if the tool type remains unchanged, at least one
relevant tool dimension has changed as compared with the deselected tool. Depending on the tool
type, relevant tool dimensions can be the tool diameter, the rounding radius or the taper angle.
Changes to the tool length are allowed.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10776 Channel %1 block%2 axis %3 must be geometry axis if tool radius
compensation is active
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: This alarm occurs when an axis that is required for tool radius compensation is not a geometry axis.
With CUT2DF, the axis can be a positioning axis perpendicular to the machining plane; with all other
types of compensation (CUT2DF, CUT3DC, CUT3DF, CUT3DFF), all geometry axes must be
operated as such.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program.
On selection of G41/42, the axes involved must be known as GEOAX in the channel. It is possible by
programming GEOAX() or G91 G0 X0 Y0 in the block prior to G41/42.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10777 Channel %1 block %2 tool radius compensation: too many blocks with
suppression of compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The maximum permissible number of blocks with active compensation suppression with tool radius
compensation is limited by the machine data CUTCOM_MAXNUM_SUPPR_BLOCKS.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: - Modify part program.
- Modify machine data.
- Check whether SBL2 is activated. 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 traversing
blocks.
Program Clear alarm with NC START or RESET key and continue the program.
