Index 0 is returned if the switchover function is disabled with:
MD35590 $MA_PARASET_CHANGE_ENABLE = 0.
In this case, the 1st parameter set is always active.

As soon as the axis/spindle has moved through the traversing distance set in machine data:
MD33050 $MA_LUBRICATION_DIST (traversing distance for lubrication from the PLC)
, the interface signal is inverted.
Note:
The distance measurement is restarted each time that the control powers up (boots).
Application
example(s)
The lubrication pump for the axis/spindle can be activated with "Lubrication pulse" interface signal.
Machine bed lubrication therefore depends on the distance traveled.

DBX92.1 Ramp function generator disable active
Edge evaluation: no Signal(s) updated: Cyclic
Signal state 1 PLC receives the signal that the ramp function generator fast stop is active.
The function has been activated by the interface signal:
DB31, ... DBX20.1 (ramp-function generator fast stop)
The drive is stopped without a ramp function with speed setpoint = 0 and without pulse suppression.
Signal state 0 Ramp function generator fast stop is not active for the drive.
Application
example(s)
Bypassing the ramp function generator on the servo side
Corresponding to ... DB31, ... DBX20.1 (ramp-function generator fast stop)
Remark In the SINAMICS a protocol can be set that runs in what is known as the 611U compatibility mode.
