NC Stop
NC Start disable
Example
4-6
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.
