is active
No program selected, program reselected,
program aborted via internal stop or program
terminated
In this condition the control has no modally effec-
tive program information (i.e. the contextual refer-
ence), so that all handling is possible, e.g. cursor
movements or modification of Q parameters.
Program started, execution runs
For safety reasons, the control permits no handling
in this condition
Program stopped, e.g. in operating mode Program
run, full sequence after pressing the NC stop key
For safety reasons, the control permits no handling
in this condition
Program interrupted, e.g. in operating mode
Positioning w/ Manual Data Input following the
error-free execution of an NC block
In this condition the control permits various
handling, e.g. cursor movements or the modifi-
cation of Q parameters. With this handling the
control may lose the modally effective program
information (i.e. the contextual reference). Loss
of this contextual reference may cause undesired
tool positions!
