Axis/spindle disable
This refers to the resulting internal state of the axis/spindle
disable. The spindle disable, which is set via the NC/PLC
interface signal DB31, ... DBX1.3 (axis/spindle disable), can
be overwritten by states such as program test
(DB21, ... DBX25.7 or DB21, ... DBX1.7) and SERUPRO,
thus generating an axis/spindle state which differs from the
NC/PLC interface signal.

Real movement means that positioning movements are
transferred to the position control.
Simulated movement means that no positioning movements
are transferred to the position control. The real machine axis
remains stationary. This corresponds to the state of an
activated axis/spindle disable or program test.
