Eliminates problems with resonant vibration of the motor/
machine by avoiding continuous operation in predefined
frequency ranges. The drive accelerates and decelerates the
Jump Freq 1
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
Eliminates problems with resonant vibration of the motor/
machine by avoiding continuous operation in predefined
frequency ranges. The drive accelerates and decelerates the
Jump Freq 2
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
Eliminates problems with resonant vibration of the motor/

Jump Freq 3
motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
Sets the dead-band width around each selected prohibited
frequency reference point.

0: Disabled 1: Enabled.
1: Enabled At power up, the drive starts the motor at the Hold frequency
that was saved.
Up/Dn LowLim Sel 0: The lower limit is determined by d2-02 or an analog input.

LCD Display
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-oo = 63).
Sets the lower limit of the frequency range where Field
Weakening control is valid. The Field Weakening command is
Field-Weak Freq valid only at frequencies above this setting and only when the
output frequency matches the frequency reference (speed
agree).
