4.2.1 Operating states
- Operating state changes on change of operating mode
At the present time, each operating mode has one of the following operating
states:
The machine is in the reset state, e.g. after switching on or after end of program
(M30).
A program has been started and program execution is running.
A program in execution has been interrupted.
A program in execution is interrupted. All state changes which occur during
NC Stop (drift of one axis in the follow-up mode or traversing an axis in
another channel) are taken into consideration after NC Start.
Here, a program can be a main program, a subroutine, a cycle or a number of
NC blocks (e.g. in MDA mode).
With certain error statuses, e.g. due to wrong parameterization of machine data,
NC START is disabled in the respective mode group (= NC START disable).
Note
The NC Start disable only applies to a single mode group.
For example, if channels 1 and 2 of mode group 1 are locked with respect to
NC start and if channel 3 belongs to mode group 3, the NC start can still
execute a program in channel 3.
If the mode changes, the operating state can also change. The following table
shows how the operating states change on change of the operating mode.
Program reset
Program running
(not in JOG mode)
Program stop
NC Stop
NC Start disable
