No. 5
No. 6
No. 7
Explanation Change the mode to the MDI or AUTOMATIC program operating mode
(VDI signal: Mode group).
Not allowed if 1. The channel is active (program running, block search, loading machine data)
2. The other program operating mode has already been started.
3. A channel has exited the mode group due to an interrupt.
4. Overstore or digitizing has been selected.
Remedy − Abort the program (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.
Explanation Automatic change from an internal mode to the mode set externally (with TEACH_IN, an
attempt is made after every stop to change from the internal mode "AUTOMATIC, MDI"
to TEACH_IN).
Not allowed if -
Remedy -
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. inter-
rupt). 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. Further interrupts of higher prior-
ity interrupt processing of the previously activated asynchronous subroutines.
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,
loading MD)
− Abort the program with the Reset key or wait until the interrupt is terminated.
−
Deactivate overstore/digitizing.
