On series Y/D rudder pedals don't move.
Yup, spot on.
Now, some aircraft have both series and parallel yaw damping.
One in particular is the Lockheed L1011.
Series yaw damping normally, however, when performing an automatic approach/land maneuver (autoland), and after approach/land track is established, the rudder yaw damping shifts to parallel operation, to aid with pilot feedback for the runway alignment and rollout function.

A superb arrangement, one that keeps the pilots in the loop at all times.
