Parameter Name No.
Skip Frequency 4 1915
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.
Setting a Frequency to 0 disables the corresponding band. Setting a Band to 0 causes the value of Band 1 to be used for this band.
