6.9 Jump frequency - jumping resonant frequencies
: Jump frequency 1
: Jumping width 1
: Jump frequency 2
: Jumping width 2
: Jump frequency 3
: Jumping width 3
• Function
Resonance due to the natural frequency of the mechanical system can be avoided by jumping the reso-
nant frequency during operation. During jumping, hysterisis characteristics with respect to the jump fre-
quency are given to the motor.

✩ Do not set the jump parameters, If multiple jump frequency setting width overlap.
✩ During acceleration or deceleration, the jumping function is disabled for the operation frequency.
