X axis shift
To shift the characteristics from a 0% = 0 rpm origin to a situation where the speed is 0 rpm at a duty of 30%:
First, determine the required CVO pin input voltage at 0%.
CVO = 6 - (4 × DUTY) = 6 - (4 × 0.25) = 6 - 1 = 5V
Determine the resistor values such that at CVO = 5 V, CVI becomes 6V.
CVO - CVI : CVI - VCC = 1 V : 6V = a ratio of 1:6.
From the above, the desired resistor values will be 20k
Ω between CVO and CVI and 80kΩ between CVI and ground.
(Due to the current capability of the CVO pin, the total resistor value must exceed 100k
Ω.)
Note that the slope will change. (In this case, since the resistor ratio is 1:6, the result will be 6/7 of (or 0.86 times) the
original slope.)
If required, the RC pin resistor value must be changed to correct the slope.
