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

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.
