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-D (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 40 with the 22-COMM-D adapter (Drive 0) is
powered down, communications with the four daisy-chained drives
(Drive 1 to Drive 4) are disrupted and the drives will fault.
• 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-D adapter will flash red. Status information from the
scanner will not indicate there is a fault at the node.
