d3: Jump Frequency
Use d3 parameters to configure the drive Jump Frequency settings.
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

≥
d3-02
≥
d3-03.

Jump Frequency
Width
This parameter sets the dead-band width around
each selected prohibited frequency reference
point. The bandwidth becomes the designated
Jump frequency, plus or minus d3-04.

d4: Frequency Reference Hold
Use d4 parameters to configure the drive frequency reference hold function.
d4-01
Frequency Reference
Hold Function
Selection
Determines if the frequency reference or
frequency reference bias is saved when the Run
command is removed or the power goes off.
0: Disabled
1: Enabled
This parameter is effective when the multi-
function inputs “Accel/Decel Ramp Hold”, “Up/
Down” or Up/Down 2”commands are selected
(H1-
= A or 10/11 or 75/76).

d4-03
Frequency Reference
Bias Step
(Up/Down 2)
Sets the bias added to the frequency reference
when the Up/Down 2 digital inputs are set.
When set to 0.00 Hz, the bias value is increased
or decreased according to d4-04.
When greater than 0.0 Hz, the bias value d4-03 is
added or subtracted to/from the frequency
reference. The acceleration or deceleration rate is
ultimately determined by d4-04.

Bias Accel/Decel
(Up/Down 2)
Selects how the bias or frequency reference is
increased when using the Up/Down 2 function.
