Commissioning Your 8720MC SERCOS Interface Drive 1-5
Configuring Your 8720MC Drive
To configure your 8720MC drive:
1. Verify that there is no power applied to the 8720MC and that the
SERCOS fiber-optic cables are plugged into the Tx and Rx
connectors. To verify your fiber-optic cable connections, refer to
the 8720MC High Performance Drive Installation Manual
(publication 8720MC-IN001x-EN-P).
2. Set the base node address for the 8720MC by setting the SERCOS
Node Address switch. Valid node addresses are 01-99. The left
hand switch sets the most significant digit (MSD) and the right
hand switch sets the least significant digit (LSD). Refer to the table
below for switch operation. Refer to Figure 1.1 for switch location.

IMPORTANT
When two or more 8720MC drives are connected
to the same 1756-MxxSE module, each node
address must be unique.
Refer to Figure 1.5 for an example of how node
addresses are assigned.
If you: Then:
Have more 8720MC node
addresses to set
Go to step 1.
Do not have more 8720MC node
addresses to set
Go to step 4.
