Frequency [Hz] = Input current [mA] x 10000 [Hz]
20 [mA]
Note the data:
Min. input frequency = __________ Hz
Max. input frequency = __________ Hz
Calculate the span factor using the formula:
Span factor [Hz / rpm] = Frequency [Hz]____________
Rotational speed of the extruder [rpm]x 10
Note the data:
Span factor = __________
