The CDS803 frequency converter generates by
design a compressor soft start with a default
initial ramp up refer to ‘Manage speed limit’.
Current inrush will not exceed the frequency
converter maximum current.
Basically seen from the mains, the inrush peak
reachs a level which is only a few percent more
than the rated nominal current.
