Interrupt routines are special --> subroutines which can be started
by events (external signals) in the machining process. The part
program block being processed is aborted and the axis position at
the instant of interruption is stored automatically.
See --> ASUB
On SINUMERIK FM--NC and 840D controls, it is possible to
program the time required to traverse the path of a block instead of
the feedrate speed for the axis movement (G93).
I/O modules create the link between the CPU and the process. I/O
modules are:
• -->Digital input/output modules
• -->Analog input/output modules
• -->Simulator modules
Control system operating mode (setup): The machine can be set up
in Jog mode. Individual axes and spindles can be jogged by means
of direction keys. Other functions in Jog mode are --> reference
point approach, --> Repos and --> Preset --> (set actual value).
1. S7- -300: The keyswitch is the mode selector switch on the
--> CPU. The keyswitch is operated by means of a removable
key.
2. 840D/FM- -NC: The keyswitch on the --> machine control panel
has 4 positions which are assigned functions by the operating
system of the control. There are also three keys of different
colors belonging to the keyswitch that can be removed in the
specified positions.
