This PI control uses ID numbers for input and output signal. See detail in PI Control chapter.
V1.27.1 PI Reference ID20
Used PI Reference, reference is selected by ID number.
V1.27.2 PI Actual Value ID21
PI Actual value. Actual input is selected by ID number.
V1.27.3 PI Output ID23
PI Output before scaling. This value uses PI Out High and Low for limiting.
V1.27.4 PI Output Scaled ID1807
Scaled PI Output.
This is used for ID connection. Scaling function is used to scale value more
suitable for connected signal. e.g. when output is connected to torque limit
actual value need to be -1000 ...+1000 (-100,0 %..+100,0 %) But PI Out High and
Low can be from -30000...+30000 to have more accurate PI control.
