Analog signal adjustment (Pr. 307, Pr. 308, Pr. 311, Pr. 312, Pr. 323, Pr. 324)
The analog output values for minimum and maximum output signals are fixed at 20% and 100% (4mA and 20mA). The output
signals at 4mA and 20mA are set using Pr. 307, Pr. 308, Pr. 311, and Pr. 312. Calibration of 4 to 20mA current output function
on bias side is set using Pr. 323, Pr. 324. See below.
