Executing Machining Programs
Distance to go < start-up distance;
Fig. 4/1 4 Distance to go positive and less than the start-up distance
Situation3
When the interruption occurs, the braking distance is already greater than the current distance to
go to the intermediate target. This means that the intermediate target of the interrupted job is
overrun, This therefore leaves a negative distance to go.
Note
tion of the interrupted job is still output, The M-function of the next job is only out-
put when the program is continued.
