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)
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 TOFFOF()
Program
Continuation:
Clear alarm with NC START or RESET key and continue the program.

Channel %1 block %3 axis %2 touch probe already deflected, edge
polarity not possible
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 (quiescent 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.
Reaction:
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
Continuation:
Clear alarm with the RESET key. Restart part program
