No NC program selected, NC program reselect-
ed, NC program aborted via internal stop, or
NC program terminated
In this state, the control has no modally effec-
tive program information (i.e., contextual refer-
ence), so that all actions are possible (e.g., cursor
movements or modification of Q parameters).

For safety reasons, the control permits no actions
in this state.
NC program stopped (e.g., in
Program run, full

key)
For safety reasons, the control permits no actions
in this state.
NC program interrupted (e.g., in
Positioning w/

operating mode, following the
error-free execution of an NC block)
In this state, the control permits various actions
(e.g., cursor movements or the modification of Q
parameters). These actions, however, may lead to
the control losing the modally effective program
information (i.e., the contextual reference). Loss of
this contextual reference may result in undesired
tool positions!
