Change the mode to a manual mode
(VDI signal (mode group): JOG, TEACH_IN, REF)
1. Nesting depth too great:
The current processing operation can be interrupted by various events (e.g. interrupt).
Depending on the event, asynchronous subroutines are activated.
These asynchronous subroutines can be interrupted in the same manner as the user pro-
gram. Unlimited nesting depth is not possible for asynchronous subroutines due to mem-
ory limitations. Example: An interrupt interrupts the current program processing. Further
higher-priority interrupts will interrupt the asynchronous programs which have been acti-
vated.
2. The channel is active (program running, block search, loading machine data)
3. A channel has exited the mode group due to an interrupt.
4. Overstore or digitizing has been selected.
> Abort the program with the Reset key
> Abort the program with the Reset key or stop the program (not with block search,
loading MD)
> Abort the program with the Reset key or wait until the interrupt is terminated.
> Deactivate overstore, digitizing
Activate overstore (PI command).

Activate overstore (PI command).

Perform user interrupt "Asynchronous subroutine" (VDI signal: digital-analog interface,
asynchronous subroutine interface)
1. The channel is active due to block search or loading machine data
2. The channel is stopped and the asynchronous subroutine "ASUP_START_MASK"
must be started and the current block cannot be reorganized.
3. Digitizing has been selected.
4. Reference point approach has not been performed yet.
5. The active block, after which deceleration takes place, cannot be reorganized (occurs
when deceleration takes place over several blocks).
> Wait until the block search or loading MD is completed, or abort program (Reset key)
> Activate a block change until the NC block can be reorganized.
> Deactivate digitizing
> Perform reference point approach or ignore this state via the MD
"ASUP_START_MASK".
> Abort program
Perform user interrupt "ASUP" with rapid retraction (VDI signal: digital-analog interface)
