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 80k
Ω
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.
