read RVB and VAL don't match when moving smarAct motors without encoders

[Juliane Reinhardt via Tech-talk <tech-talk at aps.anl.gov>]

Dear EPICS team,

I have recently been setting up smarAct MCS controllers for a couple of 
smarAct motors, some of them have encoders and some don't. The 2 motors 
that don't have encoders don't move although they are connected properly 
(I assume). When I do "caput motor.VAL 0.5" I get the feedback for old 
and new VAL and when I check with "caget motor.VAL" it matches. However, 
the actual "caget motor.RBV" does not change accordingly and the motor 
did not move.
What is required to move motors without an encoder in this case?

Thanks,
Juliane
