Fig 6.29 Frequency Bias Adjustment (Terminal A2 Input)
For example, if H3-02 is 100%, H3-03 is 0%, and terminal A2 is set to 1 V, the frequency reference from
terminal A1 when 0 V is input to A1 will be 10%.

K 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.

Jump frequency 1
Set the frequency center value at which to prohibit
settings, in hertz.
Set to 0.0 to disable the jump frequency.
Make sure the settings are as follows: d3-01 ≥ d3-
02 ≥ d3-03.
Operation within the jump frequency range is pro-
hibited. Changes during acceleration and decelera-
tion are made gradually without performing
jumps.
