Using Multi-Drive Mode

7-3

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

Figure 7.4

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

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

Figure 7.4 Multi-Drive Mode Example - With Adapter in Drive

In this case, the unit will not operate with DSI peripheral devices such as
the HIM or the 22-SCM-232 or 1203-USB and the application of any
other peripheral will be prohibited.

In

Figure 7.5

, the 22-COMM-P adapter is remotely mounted in a DSI

External Comms Kit (22-XCOMM-DC-BASE), and all PowerFlex
4-Class drives are daisy-chained from it.
