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 specific speed
range.
Function description
Minimum speed
Speeds where the absolute value is less than the minimum speed are only possible when the
motor is accelerating or braking.
Skip frequency bands
Further information on the skip frequency bands is provided in function diagram 3050 of the
