Operation Avoiding Resonance (Jump Frequency Function)

The jump frequency function operates the motor while avoiding resonance caused by characteristic frequen-
cies in the machinery.
This function is effective in creating a frequency reference dead band.
During constant-speed operation, operation within the jump frequency range is prohibited. Smooth operation
still used during acceleration and deceleration, i.e., jumps are not performed.
