8.18.4 Skip frequency bands and minimum speed
Overview
The converter has a minimum speed and four skip frequency bands:
• The minimum speed prevents continuous motor operation at speeds less than the minimum
speed.
• Each skip frequency band prevents continuous motor operation within a speci󹪝c speed
range.

Speeds where the absolute value is less than the minimum speed are only possible when the
motor is accelerating or braking.
