6.15 Jump frequency - avoiding resonant frequencies
f270 : Jump frequency 1
f271 : Jumping width 1
f272 : Jump frequency 2
f273 : Jumping width 2
f274 : Jump frequency 3
f275 : Jumping width 3
Function
Resonance due to the natural frequency of the mechanical system can be avoided by jumping the
resonant frequency during operation. During jumping, hysteresis characteristics with respect to the jump
frequency are given to the motor.

Note 1: Do not set the jump parameters, if multiple jump frequency setting width overlap.
Note 2: During acceleration or deceleration, the jumping function doesn’t work for the operation frequency.
