With this signal, all individual functions (e.g. G functions, M functions, ...) of
HMI can be inhibited.
Effect in the NC: The "1" signal has the effect that no individual block of the
MMI is executed via the NC.
Application: The signal could be used for inhibiting traversing functions
which are triggered via an individual block on the HMI, as long as the home
positions of the axes are not known.

A signal can be output for each axis in order to stop it. In the case of signal
state "1" the axis stops at its position, in the case of signal state "0" positio-
ning is allowed.
The signal is set to "0" by default.
Effect in the NC: Signal state "1" has the effect that the respective axis is not
positioned, irrespective of the feed enable. Within the control, the axis is
treated as though it is traveling. Only the actual positioning is suppressed.
The actual values are generated internally.
In the case of signal state "0", the axis is moved without restrictions, depen-
ding on other conditions. The signal is axis−specific, the other axis are not af-
fected. This also applies to path operation.
The signal should only change when the axis is stationary. If the axes are mo-
ving, the movement is stopped immediately without a ramp.
Application: Testing mode during which specific axes must not move.
