Skip frequency bands and minimum speed

Skip frequency bands
The converter has four skip frequency bands that prevent continuous motor operation within
a specific speed range. You can find additional information in function diagram 3050 of the
List Manual, see also: Manuals for your inverter (Page 387).
Minimum speed
The converter prevents continuous motor operation at speeds < minimum speed.
Speeds where the absolute value is less than the minimum speed are only possible during
motor operation when accelerating or braking.
