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
d3-01 ≥ d3-02 .

This parameter sets the dead-band width around each
selected prohibited frequency reference point. The
bandwidth becomes the designated Jump frequency,

This parameter is effective when the multi-function
inputs “Accel/Decel Ramp Hold” or “Up/Down”
commands are selected (H1-oo = A or 10/11).
