Jump frequency range
When the set frequency is in the jump frequency range, the Actual operating frequency
will run at the jump frequency close from the set frequency . The inverter can avoid
mechanical resonance point of load by setting jump frequency.
PI9000 can set two jump frequency points, if the two jump frequencies are set to 0, the
jump frequency function will be canceled. For the principle schematic of jump frequency and
its range, please refer to the following figure.

process
The function code is used to set whether the jump frequency is active or not in the
process of acceleration and deceleration.
If it is set to active, when the operating frequency is in the jump frequency range, the
Actual operating frequency will skip the set jump frequency boundary. The below figure
below shows the jump frequency status in the process of acceleration and deceleration.
