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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 MD20252 $MC_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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10778 [Channel %1: ] Block %2 preprocessing stop with active tool radius
compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: If a preprocessing stop is detected with active tool radius compensation (either programmed by the
user or generated internally) and the SD42480 $SC_STOP_CUTCOM_STOPRE is set, then this
warning is issued because in this situation machine movements which were not intended by the user
can occur (termination of radius compensation and new approach).
Reaction: Alarm display.
NC Stop on alarm at block end.
Remedy: - Continue machining with CANCEL and Start.
- Modify part program.
- Set SD42480 $SC_STOP_CUTCOM_STOPRE to FALSE.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10779 [Channel %1: ] Block %2 preprocessing stop with active tool radius
compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: If a preprocessing stop is detected with active tool radius compensation (either programmed by the
user or generated internally) and the SD42480 $SC_STOP_CUTCOM_STOPRE is set, then this
warning is issued because in this situation machine movements which were not intended by the user
can occur (termination of radius compensation and new approach).
To continue machining, activate the CANCEL key and perform a restart.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: - Continue machining with CANCEL and Start.
- Modify part program.
- Set SD42480 $SC_STOP_CUTCOM_STOPRE to FALSE.
Program Con- Clear alarm with NC START or RESET key and continue the program.
