EMC Immunity

In order to document immunity against interference
from switched electrical phenomena, the following
immunity test has been made on a system consist-
ing of a frequency converter, a screened/armoured
control cable and a control box with potentiometer,
screened/armoured motor cable, screened/armoured
brake cable and an LCP with a cable.
The tests were performed in accordance with the fol-
lowing basic standards:
• EN 61000-4-4 (IEC 1000-4-4): Burst transients
Simulation of interference brought about by
switching with contactors, relays or similar de-
vices.
