•
Use the jump frequency function to operate the
inverter while avoiding resonance points on the
load-machine system.
•
A jump frequency can be set at 3 points.
Parameter
Setting examples
•
The jump frequency function is a function to
prevent output within the specified frequency

function is input, the output is automatically limited.
While the output is limited, the LIM icon will be
displayed.
•
The output frequency within the range of the jump
frequency command fluctuates continuously
according to normal the acceleration/deceleration
time.
