d3-01 Jump
Frequency 1
d3-01 to d3-04 allow programming of three
prohibited frequency reference points for eliminating
problems with resonant vibration of the motor/
machine. This feature does not eliminate the selected
frequency values, but accelerates and decelerates the
motor through the prohibited bandwidth.
The parameters must be according to the rule
d3-01 ≥ d3-02 .

This parameter sets the dead-band width around each
selected prohibited frequency reference point. The
