Automatic speed control is linear over the range of speeds 1 to 3, while manual control simply sets a given speed.
To set speed 1 to the minimum EC motor speed, set
I64
to 0.
To set speed 3 to the maximum EC motor speed, set
I66
to 100.
To set speed 2 to the midpoint between speeds 1 and 3, set
I65
to 50.
