When the current input is selected, it is internally converted to a voltage quantity, and
its relationship is: Volt value = milliampere value/2;
6: Pulse: It can be used as PG closed-loop single-phase feedback or two-phase
feedback. Please refer to the definitions of multi-function input terminals DI4 and DI5
(terminal functions of F6.03~F6.04).

The external given signal and feedback signal often overlap a certain interference. The
channel is filtered by setting the filter time constants F8.03 and F8.04. The longer the filter
time, the stronger the anti-interference ability, but the response becomes slower; the faster
the filter time, the faster the response, but the anti-interference ability weakens.
