1.
Determine the ratio of the required minimum speed and the maximum speed.
Ra = minimum speed/maximum speed......... (1)
In the example in the figure above, Ra = minimum speed/maximum speed = 3000/10000 = 0.3
2.
Determine the product of the duty that produces the maximum speed and the value from equation 1.
Ca = maximum speed duty × Ra .................. (2)
For example, Ca = maximum speed duty × Ra = 0.8 × 0.3 = 0.24
3.
Determine the required LIM pin voltage
LIM = 6 - (4 × Ca) ....................................... (3)
For example, LIM = 6 - (4 × Ca) = 6 - (4 × 0.24)
≈ 5V
4.
Generate the LIM voltage by resistor dividing the 6 V regulator voltage.
For example, the resistor ratio to create a 5V level will be 1:5.
Thus the resistor values will be 10k
Ω between 6VREG and LIM and 51kΩ between LIM and ground.
