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 the "FREQUENCY" parameter and then programme 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 the FREQUENCY to 0 disables the corresponding band. Setting the BAND to 0 causes the value of BAND 1

to be used for this band.
