Compensation on the power supply side is not required for the variable
frequency drives of the DA1 series. From the AC power supply network they
take only very little reactive power of the fundamental harmonics
(cos ϕ ~ 0.98).
￫
In the AC supply system with non-choked reactive current
compensation devices, current deviations can enable parallel
resonance and undefinable circumstances.
In the project planning for the connection of variable frequency
drives to AC supply systems with undefined circumstances,
consider using mains chokes.
