7.18.3 Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies. The inverter will avoid specific
frequency ranges during acceleration and deceleration. Operation frequencies cannot be set
within the preset frequency jump band.
When the operation frequency is increased while the frequency parameter setting value
(voltage, current, RS-485 communication, keypad setting, etc.) is within a jump frequency band,
the frequency will be maintained at the lower limit value of the frequency band. Then, the
frequency will increase when the frequency parameter setting exceeds the range of
frequencies used by the frequency jump band.
