Danfoss VLT AutomationDrive FC 302 Installation Manual

when dealing with harmonic limits containing low harmonic numbers, the IEEE 519 limits are lower than the 61000-2-4
limits. Low harmonic drives observe the total harmonic distortion as dened in IEEE 519 for all R
sce
. Each individual
harmonic current fullls table 10–3 in IEEE 519 for R
sce
≥20.
