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.

Field Weakening Level Field-Weak Lvl
Sets the drive output voltage for the Field Weakening function
as a percentage of the maximum output voltage. Enabled when
a multi-function input is set for Field Weakening
(H1- = 63).
Default: 80%
Min.: 0

Field Weakening
Frequency Limit
Field-Weak Freq
Sets the lower limit of the frequency range where Field
Weakening control is valid. The Field Weakening command is
valid only at frequencies above this setting and only when the
output frequency matches the frequency reference (speed
agree).
Default: 0.0 Hz
Min.: 0.0
