• the machine data ($MC_TRANSMIT_BASE_TOOL..)
• the active tool length compensation (see $TC_DP..).
Whether the tool length compensation is included in the calculation depends on the work-
ing plane selected (see G17,..). The machine stops at the edge of the area where posi-
tioning is not possible.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Modify part program. Change the incorrectly specified tool length compensation.
Note: RESET alone is not enough if transformation also remains active during RESET.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21650
Channel %1 axis %2 overlaid motion not allowed
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: An overlaid motion was requested for the axis, however, this is not allowed due to the
machine data FRAME_OR_CORRPOS_NOTALLOWED.
Reactions: - Local alarm reaction.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Deselect the overlaid motion
or change machine data FRAME_OR_CORRPOS_NOTALLOWED.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
21660
Channel %1 block %2 axis %3 conflict between SYNACT: $AA_OFF and CORROF
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: When deselecting the position offset ($AA_OFF) via the part program command COR-
ROF (<axis>, "AA_OFF") an active synchronized action is detected that immediately sets
$AA_OFF for the axis (DO_$AA_OFF [<axis>] =<value>). Deselection is executed and
$AA_OFF not set again.
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
21665
Channel %1 $AA_TOFF cleared
Parameters: %1 = Channel number
Definitions: If the tool position is changed with RESET and $AA_TOFF is active during RESET, the
position offset ($AA_TOFF) is cleared.
