3.1.3 Accuracy
Accuracy is represented with respect to the maximum analog output value.
Accuracy does not change and remains within the range listed in the performance
specification even if the output characteristic is changed by changing offset/gain
settings, output range and resolution mode.
Figure 3.5 shows the range of fluctuation in accuracy when a -10 to 10V range is
selected and in normal resolution mode.
Accuracy for the analog output is within ± 0.1% (± 10 mV) when the ambient
temperature is 25 ± 5 °C and within ± 0.3% (± 30 mV) when the ambient temperature
is 0 to 55°C.

3.1.4 Conversion speed
The conversion speed for the D/A converter module is "80 s the number of
conversion enabled channels".
By setting the unused channels to D/A conversion disabled in buffer memory address
0 (Un\G0), the conversion speed can be increased.
