A potentiometer in 2-wire connection is used to define different speed settings. An additional resistor RP with value equal to the po- tentiometer is used to keep the ADC input to be ra- tiometric. In this case, the input signal for the ADC varies between 0 and VREF/2. The minimum speed corresponds to a potentiometer set to its minimum value (i.e. Rpot = 0). Maximum speed corresponds to a potentiometer set to its maxi- mum value. When the mains voltage is applied to the system, the motor starts running at a speed defined by the potentiometer, as soon as the soft start time has finished. The disadvantage of the 2-wire application is that, at maximum speed setting, the tolerance on the abso- lute value of the potentiometer defines the tolerance of the voltage at the SET input, resulting in a less accurate selection of the maximum speed setting. This can be avoided when using the 3-wire applica- tion. The voltage at SET is transferred to a 4 bit value to address a ROM table in which the different phase angles are defined with a 10 bit resolution. The 2-wire mode is selected by connecting VFB to VREF (eventually via a resistor). Note: R1, R2 and NTC are only needed for thermal pro- tection, and can be left out otherwise |
