Rockwell Automation 22-COMM-P PowerFlex Profibus Adapter - Manual (Page 27)

Installing the Adapter 2-11
The first and last node on the Profibus network needs to be
terminated by using a Profibus connector with terminating resistors
(see
Figure 2.11 ).
Some connector manufacturers offer standard terminating connectors,
such as the yellow ERNI Profibus termination vertical connector (Part #
103659). Standard Profibus node connectors, such as the Phoenix
Subcon Plus M1 (Part #2761826), can be configured as a terminating
connector by adding resistors

1. Install the required special cover on the drive. The status indicators
can be viewed on the front of the drive after power has been applied.
2. Ensure that the adapter will have a unique address on the network. If
a new address is needed, reset its switches (see Commissioning the
Adapter in this chapter).
3. Apply power to the drive. The adapter receives its power from the
connected drive and network. When you apply power to the adapter
and network for the first time, the status indicators should be green
after an initialization. If the status indicators go red, there is a
problem. Refer to
Chapter 8 , Troubleshooting .
4. Apply power to the master device and other devices on the network.

ATTENTION: Risk of equipment damage, injury, or death exists.
Unpredictable operation may occur if you fail to verify that parameter
settings and switch settings are compatible with your application.
Verify that settings are compatible with your application before
applying power to the drive.
