Additional Information
•
When the PowerFlex 525 drive with the 25-COMM-D DeviceNet
adapter (Drive 0) is powered up, all configured daisy-chained drives must
be present before an I/O connection is allowed on DeviceNet (i.e. before
the drives can be controlled).
•
If the PowerFlex 525 drive with the 25-COMM-D DeviceNet adapter
(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.
