Overview of Alarms
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Modify the RESET setting in $AA_TOFF_MODE.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
21670
Channel %1 block %2 illegal change of tool direction with $AA_TOFF active
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: If an offset has been activated in tool direction by means of $AA_TOFF[i], no block is
allowed to be activated in which the offset axis assignment i is modified (plane change,
tool change cutting tool <=> turning tool, transformation change, TRAFOOF, TCARR=0,
geometry axis change)
Reactions: - 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 TOFFOF()
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
21700
Channel %1 block %3 axis %2 touch probe already deflected, edge polarity not pos-
sible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions: The probe programmed under the keyword MEAS or MEAW is already deflected and has
switched. For a further measuring operation, the probe signal must first be canceled (qui-
escent state of the probe).
The axis display is of no significance at the present time but an axis-specific evaluation
has been planned for later stages of development.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Verify the start position of the measuring operation or check the probe signals in the PLC
interface (DB10.DBB107). Are the cables and connectors in good order?
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21701
Channel %1 block %3 axis %2 measurement not possible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number
Definitions: Measurement level 2 (MEASA, MEAWA, MEAC).
