The Class Code is “f ” for the Parameter Object and the Instance Attribute is “1”
to select retrieving the parameter value. See Parameter Object
on page 136 for
more information. The Instance value is “18541” to access parameter P109
[Accel Time 1] in the first daisy-chained drive.
The Explicit message for the other daisy-chained drives are identical except for
the Instance values, see Multi-Drive Mode Explicit Messaging
on page 111 for
examples.
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.
