d3-01
(294)
Jump Frequency 1 Jump Freq 1
Eliminates problems with resonant vibration of the motor/
machine by avoiding continuous operation in predefined
frequency ranges. The drive accelerates and decelerates the
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
Default: 0.0 Hz
Min.: 0.0
Max.: 240.0

Jump Frequency 2 Jump Freq 2
Eliminates problems with resonant vibration of the motor/
machine by avoiding continuous operation in predefined
frequency ranges. The drive accelerates and decelerates the
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.

Jump Frequency 3 Jump Freq 3
Eliminates problems with resonant vibration of the motor/
machine by avoiding continuous operation in predefined
frequency ranges. The drive accelerates and decelerates the
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
