5.6.7.4 Resonance Avoidance
PRG > 6(Tools) > 4(Resonant Avd.)
Operations can be conducted in a manner that avoids points of mechanical resonance. The inverter
operates by jumping frequencies. Resonance prevention settings are set to accomplish this. Three
resonance prevention points can be set, and the jump width can be set at one common point.

5. Pressing the
key at a point of resonance sets
resonance prevention point 1 (Fjmp1).
Note: Pressing the
key for a long period of time
changes the width (jump width). (Consistent for Fjmp1-
Fjmp3).

6. Using the key to move the cursor to Fjmp2
and pressing the key at the next point of
resonance set resonance prevention point 2
(Fjmp2).
Note: Pressing the
key for a long period of time
changes the width (jump width). (Consistent for
Fjmp1–Fjmp3).
