C2.5 Analog Output
The analog output function is available only with F3CU04-1S.
If an output terminal is not used as a control output, it may be configured for an analog
output (4-20 mA).
To configure an output terminal for analog output, set its corresponding bit in the Output
Type Selection (OUTPUT) parameter to 1 (Analog Output), and set the corresponding
Output Terminal Selection (OUTSELn) parameter (n = 1-8) to an integer ranging from 21
to 28 corresponding to AOUT1-8. To output a desired analog output level (4-20 mA), set
the corresponding Output Preset Value (AOUTn) parameter (n = 1-8) to the desired
value.
