Selection Of Analog Output Function - JPS PDA Series Instruction Manual

10. Selection of Analog output function

This section describes the definition of analog output voltage between "AM" & "ACOM".
Refer to Section-1.2.2 for the internal circuit structure.
Relative parameter
Pr.37 -- AM_SELECT
Pr.38 -- AM_GAIN
Auxiliary Analog Output Terminal "AM" is provided for analog meter display, or other applications
Requiring the analog output signal.
"AM_SELECT" is used to select desired signal, which will output to AM terminal.
"AM_GAIN" is used to fine tuning the output voltage level.
User may select any of the four signals in the Table for output to the "AM" terminal.

Gain
(Pr.38)
Desired output
signal select by Pr.37
First use Pr.37 to select desired output signal.
And let Pr.38=250.
Then adjust variable resistor for trimming to correct position.
If necessary, modify Pr.38 for fine-tuning.
Refer to Sec.1.2 for hardware structure.
Output Ratio
+5V*((Pr.57) / (Pr.15))
+5V*((Pr.59) / 1000)
+5V*((Pr.60) / (2 * Pr.84))
+5V*(PID Output)
If DIx(54)=ON, +5V*(PID Boost * (PID Output + Bias Input from AI1))
If DIx(54)=OFF, +5V*(PID Boost * PID Output)
If DIx(54)=ON, +5V*(PID Boost * (PID Output + Bias Input from AI2))
If DIx(54)=OFF, +5V*(PID Boost * PID Output)
If DIx(54)=ON, +5V*(PID Boost * (PIDoutput + Bias Input from AI3))
If DIx(54)=OFF, +5V*(PID Boost * PID Output)
If DIx(54)=ON, +5V*(PID Boost * (PID Output + Bias Set by Pr.28))
If DIx(54)=OFF, +5V*(PID Boost * PID Output)
+5V*((Pr.38)/255)
+5V*((Pr.62)/100)
