1 ) The parameter numOfUsedCams defines the interrupt cycle time (Therefore, it takes effect to
the accuracy of the track) and the behavior of the module if the DC information is lost.

2 ) The parameter resolution defines the angle resolution of the track. The value gives the
number of increments related to 360°; e. g. the value 36,000 corresponds to an angle resolution
of 0.01°.
3
) The parameter zeroShift defines the zero shift. With it the encoder can be adjusted to the
mounting position. The value of zeroShift is set in encoder-increments. It is not assigned to the
parameter resolution of the cam switch.
4 ) The parameter EncoderBitResolution defines the resolution of the used encoder (in bits), e. g.
with the default setting 18 bits the encoder has 196,608 divisions.
