Programming Parameters
D-13
47
D/A Converter 1 Output
[DAC1 Output]
This parameter contains the value that is to be
sent to the digital-to-analog converter, then to
Analog Out 1 ( TB1-7, TB1-8 [com]).
The display value (-2048 to 2047) represents the
digital value, which is proportional to the voltage
sent through Analog Out 1 (-10V to +10V).

An external analog device can be wired to Analog
Out 1 (DAC1 Output), and can read the contents
of a parameter, selected by P49 (D/A Converter 1
Source).
The quick reference chart can be used to convert
the display value into the analog output voltage.
The diagram below shows how the source
parameter value is processed using P49, P50,
P51, P52, P47, then sent to the DAC for Analog
Out.
