Using Multi-Drive Mode
For example, to access [Accel Time 1] (parameter P041 in PowerFlex 525 and
P109 in PowerFlex 4M) in each of the drives, the following slot and index values
would be used:
•
Drive 0 (PowerFlex 525) Slot = 1, Index = 41
•
Drive 1 (PowerFlex 4M) Slot = 5, Index = 109
•
Drive 2 (PowerFlex 4M) Slot = 9, Index = 109
•
Drive 3 (PowerFlex 4M) Slot = 13, Index = 109
•
Drive 4 (PowerFlex 4M) Slot = 17, Index = 109
Additional Information
•
When the PowerFlex 525 drive (Drive 0) is powered up, all configured
daisy-chained drives must be present before the 25-COMM-P adapter will
enter the Data Exchange mode. The PORT LED status indicator will flash
red while it is starting up.
•
If the PowerFlex 525 drive (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 (Drive 1 to Drive 4) are powered down,
the respective Input Image (Logic Status and Feedback) will be set to zero.
Status information will not indicate there is a fault at the node, and the
I/O connection will not be dropped.
