4.18.3 Frequency Jump
Use frequency jump to avoid mechanical resonance frequencies. The inverter will avoid
identified ranges during acceleration and deceleration. Operation frequencies cannot be set
within the pre-set frequency jump band.
When a frequency setting 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.
