Additional Information

•

When the PowerFlex 525 drive (Drive 0) is powered up, all configured
daisy-chained drives must be present before an I/O connection is allowed
on EtherNet/IP (before the drives can be controlled).

•

If the PowerFlex 525 drive (Drive 0) is powered down, communications
with the four daisy-chained drives (Drive 1 to Drive 4) are disrupted and
the drives will take their corresponding Comm Loss Actions.
