NOTE
The analog outputs only provide current outputs (0 ... 20 mA). A 0 ... 10 V voltage
signal can be generated by connecting a 500 Ohm resistor across the outputs. The
voltage drop across the resistor can be read using parameter r0774 if the
parameter P0776 is changed-over from current output (P0776 = 0) to voltage
output (P0776 = 1). The D/A scaling parameters P0778, P0780 and the D/A
converter dead zone must still be entered in mA (0 ... 20).
