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.
