INSTALLATION 2
All inputs are optocoupled, polarity insensitive, and driven by a constant current generator;
the command signal is filtered through an anti-disturbance circuit which generates a delay
which can be set to 5 ms or 500 µs. In particular, EXT_TRIG/PS, IN3 and IN4 share the
same value which usually corresponds to 5 ms when using a photoelectric sensor, while
IN2/ENC has a different value which is set to 500 µs when this input is used for the Encoder.
