4 Installation/Calibration
4.1
Mounting the sensor wheel
Note
The eccentricity of the installed sensor wheel affects the accuracy of
the whole system (see Section 3).
Do not allow permanent magnets, magnetic mounts for clock gauges, etc. to
come into contact with the sensor wheel!
Tolerances,
Permissible radial eccentricity and axial eccentricity tolerances as well as
motor shaft
position tolerances of the drilled holes, refer to Section 5.1.
Installation
The sensor wheel can be attached to the shaft by the following methods:
methods
1. Shrink fit
2. Axial screw mounting
3. Axial clamping
For information/instructions on this, refer to Table 4-1.
