• F1.03~F1.05 are used to prohibit the inverter from producing output
voltages of certain frequency ranges, in order to prevent the mechanical
vibration caused by mechanical structure as shown in Figure 5.5.
• Set F1.03~F1.05 as 0.00Hz to disable the jump frequencies.
• F1.03~F1.05 set the center values of the frequency to be jumped.
• Jump frequencies should be set so that F1.05 ¡ Â F1.04 ¡ Â
• F1.06 is used to control the jump frequency bandwidth.
• Jump frequency range = jump frequency ¡ ¾ jump frequency bandwidth

• F1.07 is used to fix the output frequency inside the jump frequency
region
• Setting
Setting
Function
constant
0
Output frequency is fixed to lower limit of jump frequency region
1
Output frequency is fixed to upper limit of jump frequency region
• During accel/decel operation, output frequency changes smoothly
without jump even though jump frequencies are activated.
