b. Calculate the desired counts for a basket speed of 24 RPMs:
C
d
= [RPM
d
* (C/RPM)] + D
C
d
= [24 RPMs * (6 counts per RPM)] + 15
159 = 144 + 15
c. Calculate the desired voltage:
V
d
= C
d
/ 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.
