.

Selections 2 and 3 select the same signals as selections 0 and 1, but instead of
providing a 5V (1/2 scale) offset to allow for a bipolar signal, no 5V offset is used.
Instead, the signal is presented in a unipolar manner. The absolute value of the
selected signal is used to drive the analog output over its full range of 0 to 10VDC.
This provides greater resolution of the selected signal at the expense of indicating
polarity. Refer to figure 4.2.

Note that in V/Hz control, signals are updated every 500 ms. In Vector control, all
signals are updated every 5.0 ms.)
