3.3.2 Incremental Input
At the incremental inputp, the counting direction depends on the phase shift
of the two signals. The maximum frequency of a single input is 1 MHz.
If pulse channel A hurries ahead the channel B by 90 degrees (like in the
picture above), an UP-counting happens. If channel B hurries ahead the
channel A by 90 degrees, a DOWN-counting happens. This can be inverted
with MKS software.
