LIM pin
The minimum speed is determined by the voltage of the LIM pin.
1) Obtain the ratio of the minimum speed required to the maximum speed.
Ra = Minimum/maximum speed … (1)
In the example shown in the figure above : Ra = minimum/maximum speed = 3000/10000 = 0.3
2) Obtain the product of the duty ratio at which the maximum speed is achieved and the value in formula (1).
Ca = Maximum speed duty ratio
× Ra … (2)
In the example given : Ca = maximum speed duty ratio
× Ra = 0.8 × 0.3 = 0.24
3) Obtain the required LIM pin voltage.
LIM = 5 - (3
× Ca) … (3)
In the example given : LIM = 5 - (3
× Ca) = 5 - (3 × 0.24) ≈ 4.3V
4) Divide the resistance of 5VREG to generate the LIM voltage.
In the example given, the voltage is 4.3V so the resistance ratio is 1 : 6.
The resistance is 10k
Ω between 5VREG and LIM and 62kΩ between LIM and GND.
