Using Multi-Drive Mode Chapter 7
Parameter Read Message Configuration
Parameter Write Message Configuration
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 “18541” to access parameter P109
[Accel Time 1] in the first daisy-chained drive.
The Explicit message for Drive 1 to Drive 4 are identical except for the Instance
values, see Multi-Drive Mode Explicit Messaging
on page 82 for examples.
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.
