Interrupt signals
• A total of 8 interrupt signals (inputs) are available.
• All inputs can be controlled via the PLC.
• The first four interrupt signals are also controlled via the 4 rapid NC inputs of the NCU module.
• The signal status of the rapid NC inputs can be read out via the PLC interface (DB10).
• The transmission of the rapid NC input signals to the interrupt signals can be disabled via the PLC interface
(DB10).

Call of interrupt routines
During program operation
It is possible to call the interrupt routines, when the mode groups are present in program operation. This means
that the processing is done either in the mode type AUTOMATIC or MDA part program blocks.
Outside the program operation
Interrupt routines can also be activated in the following program statuses or mode types:
• JOG, JOG REF
• MDA Teach In, MDA Teach In REF, MDA Teach In JOG, MDA REF, MDA JOG
• AUTOMATIC, stopped, ready
• Not referenced
If an interrupt routine is activated in JOG or REF mode, it will interrupt any jogging and referencing operations in
progress.
