Possible mounting positions for sensor B would be, for example:
Position sensor A + 1,33 * P; 2,33 * P; 3,33 * P; 4,33 * P; ...
and for sensor C:
Position sensor A + 1,66* P; 2,66 * P; 3,66 * P; 4,66 * P; ...
Influence of mounting errors on the phase shift
For the correct operation of either function 'Detection of rotational direction' and 'Pulse
comparison', the deviation of the phase shift must not exceed 5° of the calculated
mounting position.
