When the origin in the speed control diagram is set so that the motor starts turning when the duty is above 0%. the
potential difference between the CVO pin and VCC is resistor divided, and that divided level is input to the CVI pin.
The duty at which rotation starts can be changed by changing the resistor ratio.
Note that the total value of the resistors R4 and R5 must exceed 100k
