Analog Output Units
Section 9-3
Analog Output Signal
Ranges
The analog values depend on the output signal ranges, as shown in the fol-
lowing diagrams.
Note
When the output exceeds the specified range, the output signal will be fixed at
either the lower limit or upper limit.

10 to 10 V
When the resolution is 1/6,000, the hexadecimal values F448 to 0BB8 (–3000
to 3000) correspond to an analog voltage range of –10 to 10 V.
The entire output range is –11 to 11 V.
Specify a negative voltage as a two’s complement.
