FUNCTION CODES
Chap 5
■ Gain
To input bipolar analog voltage (0 to ±10 VDC) to terminal [12], set C35 data to “0.” Setting C35 data to
“
1” enables only the voltage range from 0 to +10 VDC and interprets the negative
polarity input from 0 to
-
10 VDC as 0 V.
■ Terminal [C1] (C1 function) range / polarity selection(C40)
Selects the range of current input terminal [C1](C1 function).
C40 data Terminal input range When specified bias is negative
0 4 to 20 mA (factory default)
Limits a point lower than 0 to 0.
1 0 to 20 mA
10 4 to 20 mA
Makes a point lower than 0 effective as a negative
value.
11 0 to 20mA
For using terminal [C1] for the C1, V2 or PTC function, it is necessary to make the settings as shown below.
Terminal [C1] SW3 SW4 E59 H26 C40
For use of C1 function (4 to 20 mA) C1 AI 0 0 0, 10
For use of C1 function (0 to 20 mA) C1 AI 0 0 1, 11
For use of V2 function (0 to +10V)
V2 AI 1 0
