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.
