F7 = Rotation direction; channel B must replicate channel A with a phase difference. Includes only the parameters related to the displayed scale, if the function is F2-F6: the electric limits of channel B are the same as channel A. PreS= the prescaler is the weight of the impulse, that is the value of counter increase at each impulse. FUNCTIONS: "EEE" or "Err" is displayed when at least one of the two inputs or the result of the function is in "EEE" or "Err" condition.
