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 is also used for deadband control.

Jump frequency 1
Set the frequency center value at which to prohibit set-
tings.
Set to 0.0 to disable the jump frequency.
Make sure 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.
