7.8 Optical rotational speed/angle of rotation measuring
system (option)
As the stator with the optical rotational speed sensor only partially encloses
the slotted disc, if there is sufficient space available for installation, you can
subsequently move the stator tangentially over the ready-mounted rotor.
For perfect measuring mode, the slotted disc of the rotational speed
measuring system must rotate at a defined position in the sensor pickup.
7.8.1 Axial alignment
There is a mark (orientation line) in the sensor pickup for axial alignment.
When installed, the slotted disc should be exactly above this orientation line.
Divergence of up to "2 mm is permissible in measuring mode (total static
and dynamic displacement).
