Harmonics are below the limits defined in IEEE 519-2014, and G5/4. The drive
complies with IEC 61000-3-2, IEC 61000-3-4 and IEC 61000-3-12. Harmonic distortion
The table below shows typical values of the drive for short-circuit ratio ( I
sc
/ I
1
) of 20
to 100. The values will be met if the supply network voltage is not distorted by
other loads and when the drive operates at nominal load.
THDv (%) THDi (%) Nominal bus voltage V at PCC
< 3** 3* V ≤ 690 V
Point on a public power supply system, electrically nearest to a particular
load, at which other loads are, or could be, connected. The PCC is a point
located upstream of the considered installation. PCC
Indicates the total harmonic current distortion of the wave form. This value
is defined as the ratio (in %) of the harmonic current to the fundamental
(non-harmonic) current measured at a load point at the particular moment
when the measurement is taken:
