Using Multi-Drive Mode Chapter 7

• Since the RS-485 ports are used for daisy-chaining the drives, there is no

connection for a peripheral device such as a HIM or USB converter

module (1203-USB). DSI Splitter cables cannot be used to add a second

connection for a peripheral device.

System Wiring

To daisy-chain the drives to the PowerFlex 525, the AK-U0-RJ45-TB2P terminal

block connector can be used for easy installation.

The wiring diagram for using AK-U0-RJ45-TB2P terminal block connectors is

shown below.

The AK-U0-RJ45-TB2P comes with (5) terminal block connectors and (2)

terminating resistors.

Understanding the I/O Image

The terms input and output are defined from the master’s point of view.

Therefore, output I/O is data that is output from the master and consumed by

the PROFIBUS DP adapter. Input I/O is status data that is produced by the

adapter and consumed as input by the master.

The I/O image table will vary based on the configuration of Host parameters

C169 [MultiDrv Sel] and C175 [DSI I/O Cfg]. The image table always uses

consecutive words starting at word 0.

The Multi-Drive Example of I/O Image

on page 58 is an illustration of the

Multi-drive I/O image with 16-bit words.
