Overview of Alarms
NCK alarms
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 reference point)
changes, is only permissible in straight and polynomial blocks.
It is impermissible in circular blocks, involute blocks and in blocks including rational polynomials with
maximum permissible numerator and denominator degrees.
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.
tinuation:
10781 [Channel %1: ] Block %2 illegal orientation of involute with tool radius
compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Tool radius compensation is possible for involutes only if the compensation plane matches the invo-
lute plane.
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10782 [Channel %1: ] Block %2 illegal curve type with tool radius compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm occurs, if an attempt is made to apply the tool radius compensation to a curve type for
which this function is not implemented. The only cause at present: Involute with 3D tool radius com-
pensation.
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
