DCS 500 Software Description 9
Analog Outputs There are three analog output channels. Connections are made to
either SDCS-CON-2 or SDCS-IOB-3 boards. The first two outputs
(AO1 and AO2) are programmable, and the range of the outputs is
+10V...-10V. The third output is an armature current actual measu-
rement from the HW-circuit. For more detailed information, see
TECHNICAL DATA.

Example:
If the signal SPEED ACT (12102) is used in the analog output1,
the settings are:
AO1 [IN] (201) = 12102
AO1 NOMINAL V (202) = 10
AO1 OFFSET V (203) = 0
AO1 NOMINAL VAL (204) = 20 000
With these settings the actual speed value 20000 corresponds to
+10V output voltage.
