ABSTRACT:
The interface circuit has a single input terminal for receiving an analog or digital control signal indicative of the required speed of rotation of the motor. The type of input signal is recognised by means of comparator circuits. The input signal is processed differently according to its nature in order, in any case, to output an analog signal acceptable by the regulation and control circuit which pilots the motor.
