(4-3) Z Position Nosepiece Rotation Stop
(See DS-L3 Chapter 6 "5.3 Disabling the Rotation of the Motorized Nosepiece Depending on the Position of the
Elevating Section".)
This function is to prevent the objective from contacting the specimen.

The configured upper limit is applied to all the nosepiece addresses.
In order to set the rotation stop, a motorized nosepiece must be attached.
