D-100
AC30V series Variable Speed Drive
Skip Frequencies
Setup::Application::Skip Frequencies
Function availability depends on macro selected.
This function is used to prevent the Drive operating at frequencies that cause mechanical resonance in the load.
PNO Parameter Descriptions
Skip Freq Band 1

Skip Frequency 1
The centre frequency of skip band 1 in Hz.
Skip Freq Band 2
The width of skip band 2 in Hz.
Skip Frequency 2
The centre frequency of skip band 2 in Hz.
Skip Freq Band 3
The width of skip band 3 in Hz.
Skip Frequency 3
The centre frequency of skip band 3 in Hz.
Skip Freq Band 4
The width of skip band 4 in Hz.
Skip Frequency 4
The centre frequency of skip band 4 in Hz.
Functional Description
Four programmable skip frequencies are available to avoid resonances within the mechanical system. Enter the value of frequency that causes
the resonance using a
Frequency
parameter and then program the width of the skip band using its
Band
parameter. The Drive will then avoid
sustained operation within the forbidden band as shown in the diagram. The skip frequencies are symmetrical and thus work in forward and
reverse.
