Jump Frequency Function (Operation Avoiding Resonance) - Omron VARISPEED E7 User Manual

Jump Frequency Function (Operation Avoiding Resonance)

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.

The relationship between the output frequency and the jump frequency reference is as follows:
Output frequency
Setting Precautions
Set the jump frequencies according to the following formula: d3-01 ≥ d3-02 ≥ d3-03.
•
When parameters d3-01 to d3-03 are set to 0 Hz, the jump frequency function is disabled.
