EMC is a highly complex topic for which there is no general answer. EMC interference may occur in the control inputs (digital/analogue input, encoder, bus system), and may lead to unwanted signals, faults or even damage. In case of problems, contact a qualified EMC specialist. General measures to avoid EMC: Proper shielding of the frequency inverter minimises electromagnetic interference Components for interference suppression such as filters, chokes and capacitors can reduce noise and electromagnetic emissions Use well-shielded high-quality cables, and minimise long cable lines Proper earthing minimises electromagnetic interference (e.g. TI 80_0019) The installation should be done according to the manufacturer’s instructions and the relevant standards (e.g. TI 80_0019, TI 80_0011) Separation of high-voltage and low-voltage cables The mains must be balanced Twisting of wires Cable ferrites can be used to reduce existing interference
