1.2.3.2.3.2.1 Radial displacement (r)
This basically means sliding the encoder chip off the scanning track. Deviations within the permissible range
increase the narrow angle error amplitude. This can be compensated by calibration. Moving the chip closer to
the center of the ring will have the most effect due to a direct influence on the main positioning (Master) track.
The other direction will mostly reduce the absolute position accuracy. If increased more than specified values,
the chip might fail sensing the magnetic field and throw an error.
