6 Functional description
6.1 Position measurement
Position measurements are taken from the evaluation of an incremental pulse
position transducer with 2 pulse signals (A, B), which are phase-shifted by 90°.
All edges can be evaluated. The possible resolution amounts 1/4 of the period's
duration (4-fold evaluation). The type analysis can be choosen in the configu-
ration.
