b.Calculate the desired counts for a basket speed of 24 RPMs:

Cd = [RPMd * (C/RPM)] + D

Cd = [24 RPMs * (6 counts per RPM)] + 15

159 = 144 + 15

c. Calculate the desired voltage:

Vd = Cd / 409.5

0.3883 = 159 / 409.5

2.The DC voltage measured at the output terminals of the D-to-A board and at analog voltage input terminals FV and FC on the inverter (shown in Figure 2) should match this number. You may see a small voltage drop from the D-to-A board to the inverter.
