Rockwell Automation 1769-SM2 Compact I/O DSI/Modbus Communication Module - Manual (Page 33)

Installing the Module 2-11
When connecting a drive to the channel port using 22-RJ45CBL-C20
communications cable, the above drive parameters do not require
configuration because the drive senses that a DSI peripheral is connected
and it ignores these parameter settings.
Multi-Drive Mode
For Multi-Drive mode, each channel port MUST be connected to the
drives via daisy-chaining using AK-U0-RJ45-TB2P terminal block
connectors (one for the port connection and one for each drive
connection) and twisted pair network wiring (Belden No. 3105A or
equivalent). The 22-RJ45CBL-C20 communications cable and splitter
cables cannot be used.
Important: The following drive parameters MUST be configured to the
settings shown so that the 1769-SM2 module will
communicate with the drives:
Changes to these drive parameters require the drive to be
reset for the new settings to take effect.
