Rockwell Automation 22-COMM-P PowerFlex Profibus Adapter - Manual (Page 70)

7-10 Using Multi-Drive Mode
The following table shows example settings for all five drives on the
node:
Important: Parameter A105 - [Comm Loss Action] in the drives that
are daisy chained is also used in Multi-Drive mode. If the
RS-485 daisy-chain cable is disconnected or broken, the
disconnected drives will immediately take the
corresponding Comm Loss Actions. Drive parameter A106
- [Comm Loss Time] is not used in Multi-Drive mode. For a
network disruption, adapter Parameters 09 - [Comm Flt
Action] and 10 - [Idle Flt Action] determine the action
taken for ALL of the drives on the Multi-Drive node.
P arameter addressing for Parameter Data in Multi-Drive mode is similar
to that in Single mode.
The parameter numbers (PNU) range from 1 to 2047. The parameter
numbers 1…1023 are used to access the drive or adapter parameters,
while parameter numbers 1024…2047 are used for accessing the adapter
fault codes, events and diagnostic items.
For details to access the drive parameters when the adapter is operated in
of Multi-Drive mode, see
Parameter Message Request on page 6-4 .
