Frequency jump

To avoid system’s mechanical resonance frequency when running the motor, the inverter provides three sets of
jump frequencies: 01-16(P.91) and 01-17(P.92) (the first set), 01-18(P.93) and 01-19(P.94) (the second set),
01-20(P.95) and 01-21(P.96) (the third set)


For example: assuming 01-16(P.91)=45 and 01-17(P.92)=50;
If the target frequency ≤ 45Hz, then the steady output frequency = the target frequency.
If 45Hz ≤ target frequency ＜ 50Hz, then the steady output frequency = 45Hz.
If the target frequency ≥ 50Hz, then the steady output frequency = the target frequency.
Note: 1. During acceleration / deceleration, output frequency of inverter will pass through the jump frequency.
2. When 01-16(P.91)=99999 or 01-17(P.92)=99999, the first set of frequency jump is invalid.
When 01-18(P.93)=99999 or 01-19(P.94)=99999, the second set of frequency jump is invalid.
When 01-20(P.95)=99999 or 01-21(P.96)=99999, the third set of frequency jump is invalid.
