[D/A #x Value]
The unscaled value of the data that will be output
on the D/A channel. This parameter must be the
destination of link for any data to be output. All
data output is treated as a signed word.

[DC Link Setup]
This parameter selects the mode of operation for
systems fault detection. Unless DC Link is
shared, "standard" should be selected.

[Desired BW]
This is associated with the auto tune function and
allows you to enter a desired velocity bandwidth
less than or equal to the [Max Bandwidth]
parameter as calculated by the auto tune cycle.

[Dig Cmd Mode]
This parameter determines whether digital
velocity commands are treated as signed
(Bipolar) inputs, or unsigned (Unipolar). If
unipolar operation is selected, velocity direction
is selected by the discrete direction commands.
