P2.41 Skip freq. band 3
Setting range
Setting of above parameters is mainly used for avoiding mechanical resonance due to
the inverter running on the resonant frequency points. When the skip frequency is set,
the inverter will skip from the frequency points set them during running. No matter
accel and decel,speed,the frequency of inverter will pass these points. If the skip
frequency range is set to 0, the corresponding resonant frequency point has no
function of skip. The output frequency of inverter can perform skip operation at some
frequency points, shown as Diagram 6-10.

P2.42 Carrier frequency selection
Setting range
This parameter is used for setting carrier frequency of PWM wave by inverter output.
Carrier frequency will affect the noise of the motor running.In the mute occasion ,it is
0.0—Upper limit frequency
0.0—10.0Hz
