Frequency Detection 1
Output frequency ≥ Frequency Detection Level n095
(Set n057, n058 or n059 to 4.)
Frequency Detection 2
Output frequency ≤ Frequency Detection Level n095
(Set n057, n058 or n059 to 5.)
 Jump Frequencies (n083 to n086)
This function allows the prohibition or “jumping” of critical frequencies
so that the motor can operate without resonance caused by the machine
system. This function is also used for dead band control. Setting the val-
ues to 0.00 Hz disables this function.
Set prohibited frequencies 1, 2, and 3 as follows:
Operation is prohibited within the jump frequency ranges.
However, the motor will operate without jumping during acceleration/
deceleration.
