7-22 Using Multi-Drive Mode
The Class Code is “ f ” for the Parameter Object and the Instance
Attribute is “1” to select retrieving the parameter value. See
Appendix C ,
Parameter Object for more information. The Instance value is “17447” to
access Parameter 39 - [Accel Time 1] .
The Explicit messages for Drive 1 to Drive 4 are identical except for the
Instance values:
Drive 1 Instance = 18471 (18432 + 39)
Drive 2 Instance = 19495 (19456 + 39)
Drive 3 Instance = 20519 (20480 + 39)
Drive 4 Instance = 21543 (21504 + 39)
•
When the PowerFlex 40 with the 22-COMM-E (Drive 0) is powered
up, all configured daisy-chained drives must be present before an I/O
connection is allowed on EtherNet/IP (i.e. before the drives can be
controlled).
•
If the PowerFlex 40 with the 22-COMM-E 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.
•
If any of the daisy-chained drives (Drive1 to Drive 4) are powered
down, the respective Input Image (Logic Status and Feedback) sent to
the scanner will be zeros, and the NET A and PORT LEDs on the
22-COMM-E adapter will flash red. Status information from the
scanner will not indicate there is a fault at the node, and the I/O
connection will not be dropped.
