n
In a rotational movement of the system, the sensors generate a specific number of
pulses. These are a measure of the covered angel or way. With the electrical phase
shift of the two signals the direction of rotation can be determined.
–
If the axis rotates to the right, then the signal of
Track A
is leading 90° towards the
signal of
Track B
.
–
If the axis rotates to the left, then the signal of
Track A
is lagging 90° towards the
signal of
Track B
.
n
During the sensor evaluation from the difference between two counter values the
velocity and direction can be determined.
n
With
1-fold
evaluation one signal edge 0-1 of
Track A
corresponds to one counter
pulse respectively one division of the system to be scanned corresponds to one
counter pulse.
n
With
4-fold
evaluation one signal edge of
Track A
and
Track B
corresponds to one
counter pulse. The 4-fold evaluation is very often used.
