Output Signal
The quadrature output operates with a phase displacement between signals A/A’ and B/B’.
In case of a quadrature type input signal with 90° phase shifting according to
, the output
appears with the same displacement of 90°. However, with inputs according to
, the
phase displacement at the output will be constant in time, therefore will correspond to 90° only
at a certain input frequency and will become smaller with lower input frequencies.
This in general, this is not a restriction for proper detection of the direction, because most of
the controllers can clearly interpret this information, even when the phase is barely visible on
an oscilloscope.
DIL switch slider S1 permits selection of 5 different times. The frequency is shown in brackets
at which the phase displacement corresponds to 90°.
