Overview of Alarms
Remedy: • Modify part program.
• Modify machine data.
• Check whether SBL2 is activated. With SBL2, a block is generated from each part pro-
gram 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 pro-
grammed by the user or generated internally) and the setting data
$SC_STOP_CUTCOM_STOPRE is set, then this warning is issued because in this situa-
tion machine movements which were not intended by the user can occur (termination of
radius compensation and new approach).
Reactions: - Alarm display.
- NC Stop on alarm at block end.
Remedy: • Continue machining with CANCEL and Start.
• Modify part program.
• Set setting data $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 pro-
grammed by the user or generated internally) and the setting data
$SC_STOP_CUTCOM_STOPRE is set, then this warning is issued because in this situa-
tion 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.
Reactions: - 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 setting data $SC_STOP_CUTCOM_STOPRE to FALSE.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10780
Channel %1 block %2 impermissible change of a turning or grinding tool with
active tool radius compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A tool change on which the edge offset (difference between edge center and edge refer-
ence point) changes, is only permissible in straight and polynomial blocks.
It is impermissible in circular blocks, involute blocks and in blocks including rational poly-
nomials with maximum permissible numerator and denominator degrees.
