AC890PX AC Drive
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.
NOTE
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.
