Using Multi-Drive Mode
This chapter provides instructions on how to configure a CompactLogix
controller to use the PowerFlex 520-series drive in Multi-drive mode.
Single-Drive Mode vs. Multi-
Drive Mode Single-drive mode is a typical network installation, where a single PROFIBUS
node consists of a single drive with a PROFIBUS adapter.
Single-Drive Mode Example for Network
Multi-drive mode is an alternative to the typical network installation, where a
single PROFIBUS node can consist of one to five drives (see
Multi-Drive Mode
Example for Network on page 56 ). The first drive must be a PowerFlex 520-series
drive. The remaining drives can be any PowerFlex drive which supports Multi-
drive mode.
