Operation Avoiding Resonance (Jump Frequency Function)
• This function allows the prohibition or “jumping” of certain frequencies within the Inverter’s output fre-
quency range so that the motor can operate without resonant oscillations caused by some machine systems.
• It can also be used for deadband control.
Related Constants
The relationship between the output frequency and the jump frequency reference is as follows:
Fig 6.23 Jump Frequency
Setting Precautions
• Set the jump frequencies according to the following formula: d3-01 ≥ d3-02 ≥ d3-03.
• When constants d3-01 to d3-03 are set to 0 Hz, the jump frequency function is disabled.

d3-01 Jump frequency 1
Set the frequency center value of the jump frequency set-
tings, in hertz.
Set to 0.0 to disable the jump frequency function.
Make sure that the settings are as follows: d3-01 ≥ d3-02 ≥
d3-03.
Operation within the jump frequency range is prohibited.
Changes during acceleration and deceleration are made
gradually without performing jumps.
