Because of the quadruple evaluation of the incremental encoder, furthermore it possible to
divide this value by the factor four. Then a value of 3141.6 increments per revolutions results.
As there is no such incremental encoder, the incremental encoder with the next higher number
of increments is used. In this example one would use an incremental encoder with 4096
pulses/revolution to maintain the required accuracy of 0.5 mm.
The accuracies specified and to be expected only can be considered with regard to the
electrical system and do not include the mechanical conditions, as for instance gearbox
backlashes.
