Input signals

Tracks C and D are giving an absolute signal to the control unit. The period is correspond
exactly to one mechanical revolution of the encoder. At starting the control unit will start
with this relative inaccurate absolute value. With the first zero pulse the position will be cor-
rected. Thus approach to reference point is not necessary.
