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:
<1> <2>

Limits how much the frequency reference is allowed to change
while an input terminal set for Up 2 or Down 2 is enabled. If
the frequency reference changes for more than the set value,
then the bias value is held and the drive accelerates or
decelerates to the frequency reference. Set as a percentage of
