5.4.8 ADV-27 Frequency Jump
Use jump frequencies to avoid mechanical resonance frequencies. Jump through up to three
frequency bands during acceleration and deceleration. Reference frequencies cannot be set
within the pre-set jump frequency band.
When the reference frequency is increased it will be maintained at the lower limit of a jump
frequency band. As the reference frequency continues to increase and exceeds the range of a
jump frequency band, it will jump to the upper limit of the jump frequency band. Decreasing
reference frequencies operate in the same it will manner, jumping from upper limit to lower limit.
Jump frequencies apply to all reference frequency sources (voltage, current, RS-485
communication, keypad setting).

When ADV-24 (Freq Limit) is set to ‘Yes,’ the frequency set at ADV-25 (Freq Limit Lo) is the
minimum frequency (Low Freq). If ADV-24 (Freq Limit) is set to ‘No,’ the frequency set at
DRV-19 (Start Freq) becomes the minimum frequency.
When ADV-24 (Freq Limit) is set to ‘Yes,’ the frequency set at ADV-26 (Freq Limit Hi) is the
maximum frequency (High Freq). If ADV-24 (Freq Limit) is set to ‘No,’ the frequency set at
DRV-20 (Max Freq) becomes the maximum frequency.
