They are especially effective where radiated emissions from long drive to motor cables are a problem e.g. corruption of near by control or data cable signals or radio / television interference. The correct fitting of a PFO choke into the motor cable can eliminate these problems. The table above gives approximate motor kW ratings for the chokes but the selection is ultimately governed by the type and thickness of motor cable fitted i.e. the motor cable must fit through the PFO choke centre hole. Occasionally EMC problems will occur within an installation when components in the same wiring enclosure affect one another, for example, open control boards may corrupt low level sensor signals. Usually in these cases the fitting of additional chokes into the control and sensor cables will cure the problem - a small amount of experimentation may be required to determine the optimum configuration of these additional chokes.
