No. 7
Explanation Change the mode to a manual mode
(VDI signal (mode group): JOG, TEACH_IN, REF).
Not allowed if 1. Nesting depth too great:
The current processing operation can be interrupted by various events (e.g., interrupt).
Depending on the event, ASUBs are activated.
These ASUBs can be interrupted in the same manner as the user program. Unlimited
nesting depth is not possible for ASUBs due to memory limitations. Example: An interrupt
interrupts the current program processing. Other interrupts with higher priorities interrupt
processing of the previously activated ASUBs.
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.
Remedy > Abort the program with the Reset key.
> Abort the program with the Reset key or stop the program (not with block search, load-
ing machine data).
> Abort the program with the Reset key or wait until the interrupt has finished.
> Deactivate overstore/digitizing.

Explanation Perform user interrupt "ASUB" (VDI signal: Digital-analog interface, ASUB interface).
Not allowed if 1. The channel is active due to block search or loading machine data.
2. The channel is stopped, the "ASUP_START_MASK" ASUB must be started and the
current block cannot be reorganized.
3. Digitizing has been selected.
4. Homing has not yet been performed.
5. The active block, after which deceleration takes place, cannot be reorganized (occurs
when deceleration takes place over several blocks).
Remedy > Wait until block search or loading machine data has finished or abort program (Reset
key).
> Activate a block change until the NC block can be reorganized.
> Deselect digitizing.
>Perform homing or ignore this state via the "ASUP_START_MASK" MD.
> Abort the program.
No. 11
Explanation Perform "ASUB" user interrupt with rapid retraction (VDI signal: Digital-analog interface).
