6.3.10 Frequency Detection (n073)
Effective when multi-function contact output selections n040 or n041 are set to frequency detection (Setting: 4 or 5).
Frequency detection turns ON when output frequency is higher or lower than the frequency detection level (n073).
§ Frequency Detection (Output Frequency << Frequency Detection Level)
(Set n040 or n041 to 4.)
Figure 29 Frequency Detection Example
(Fout ≤ Freq Detection Level)
§ Frequency Detection (Output Frequency >> Frequency Detection Level)
(Set n040 or n041 to 5.)

(Fout ≥ Freq Detection Level)
6.3.11 Jump Frequencies (n058 to n060)
This function allows the prohibition or “jumping” of critical frequencies so that the motor can operate without resonance
caused by machine systems. This function is also used for dead band control. Setting the value to 0.0Hz disables this
function.
Set jump frequency 1 or 2 as follows:
n058 < n059 − n060
If this condition is not satisfied, the Inverter displays constant setting error OPE6.
