NOTE
The analog output only provides the current output (0 ... 20 mA). A 0 ... 10 V
voltage signal can be generated by connecting a 500 Ohm resistor across the
output.
With parameter P0775 = 1, negative values can be avoided on the input side of the
DAC channel. If this parameter is activated, the absolute value is always entered in
the input of the DAC scaling (the DAC characteristic is mirrored on the Y axis).
If the value was originally a negative one, the corresponding bit in r0785 is set for
detection.
