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.
