Using Multi-Drive Mode

Figure 7.1 Single Mode Example for Network

Multi-Drive mode is an alternative to the typical network installation,
where a single ControlNet node can consist of one to five drives. In

Figure 7.2

, the 22-COMM-C adapter is internally mounted in a

PowerFlex 40/400 drive, and the remaining PowerFlex 4-Class drives are
daisy-chained from the RS-485 port on the first drive. In

Figure 7.3

, the

22-COMM-C adapter is externally mounted in a DSI External Comms
Kit, and all PowerFlex 4-Class drives are daisy-chained from it.
