EMC Immunity
In order to document immunity against electrical interference, the following immunity tests have been made on a
system consisting of a frequency converter, a screened/armoured control cable and a control box with potenti-
ometer, screened/armoured motor cable, screened/armoured brake cable and an LCP 2 with a cable.
The tests were performed in accordance with the fol-
lowing basic standards:
•
EN 61000-4-4 (IEC 61000-4-4): Burst transients Simulation of interference brought about by switching
with contactors, relays or similar devices.
•
EN 61000-4-5 (IEC 61000-4-5): Surge transients Simulation of transients brought about e.g. by lightning
that strikes near installations.
•
EN 61000-4-2 (IEC 61000-4-2) : Electrostatic discharges (ESD)Simulation of electrostatic discharges
from human beings.
•
EN 61000-4-3(IEC 61000-4-3): Incoming electromagnetic field radiation, amplitude modula-
ted.Simulation of the effects of radar and radio broadcast devices as well as mobile communication
devices.
•
VDE 0160 class W2 test pulse: Mains transients Simulation of high-energy transients generated by
breaks in master fuses, connection to phase advancer batteries and the like.
•
EN 61000-4-6 (IEC 61000-4-6): RF Common mode Simulation of the effect from radio-transmitting
equipment connected to connection cables.
