Chapter 7 Basic Functions
(1) ADV-24 Freq Limit: If you set the frequency as Yes with the initially set value being No, you can set the
frequency only between the upper limit(ADV-25) and lower limit(ADV-26). With frequency set as No, ADV-25 and
ADV-26 codes are not displayed.
(2) ADV-25 Freq Limit Lo, ADV-26 Freq Limit Hi: sets the upper and lower limits. The minimum set value of the
upper limit is the lower limit and the maximum value of the lower limit is the upper limit.

3) Frequency Jump (Avoiding mechanical resonant frequency)
Frequency jump is for prohibiting frequency setting so that the inverter does not operate in the resonant frequency
band which might occur to the user’s device system. The frequency passes through the frequency jump band when
the motor accelerates or decelerates and cannot be set within the set frequency jump band.

If you want to increase the frequency, if the set frequency(current, voltage, RS485 communication, keypad setting,
etc.) is within the jump frequency band, keep the frequency jump lower value and raise the frequency after the set
frequency goes out of the frequency jump band.
