Analog Outputs

The combined I/O board contains one user-configurable analog output. The
output is configurable using inverter parameters Anlg Out Config through
Analog Out1 Lo (340...344). The analog output has two modes: voltage (output
at -10 V...10 V) and current (output at 0 mA...20 mA). Separate terminals on the
combined I/O board are used for each mode.

The mode is selected via inverter parameter Anlg Out Config (340). In this
parameter, if the lowest bit is set to 1, then the analog output is in voltage mode;
if set to 0 it is in current mode.

The following table describes the correspondence between the mode of the
user-configurable analog output and the combined I/O board terminals that
should be used.

The combined I/O board contains two special purpose analog outputs: AO1 and
AO2. These outputs are not user-configurable.
