10.7.2 PID feedback
-
PID feedback source is selected in H50 code. PID feedback means a kind of physical value like
pressure, so it should be one of analog inputs.
-
For PID feedback, several codes are used. Analog gain, bias, filters are first. Scaling for real
value display is second. And there is additional code in drive group only for display.
