Mode management
- PRIORITY Modes:
STOP_Cam> Homing > Positioning > Setup
(The transitions occur "on the fly"; the priority always
applies, even with simultaneous mode selection;
"Homing on the fly" is always possible).
- REF_TYPE determines the type of homing, only
evaluated when edge of REF_ON is positive
(REF_ON starts homing).
- On switchover to "Constant set-setpoint-transfer"
(SPV_RIE_TYP = 1) all the above setpoint inputs are
are always immediately switched through.
- With "Constant set-setpoint-transfer" NO relative
postioning is possible (KK0874 (see above) is set to 0%).

Evaluation STOP cam:
(From V2.21)
After the enable, the limit switches act continually on the valid
modes to interlock the movements (V=0).
Static STOP cam (from V2.40):
In this mode overtravel of the cam is not supported which is why the
cams must be executed up to the end stop!
