6.
Connect the PROFINET CAT 5e communication cable to the option connector
(CN1) port 1.
To connect the option to a network, firmly connect RJ45 8-pin Shielded Twisted Pair
CAT 5e cable(s) into the modular connector ports (see Figure 7 ). Refer to Network
Topology and Connections on page 21 .
NOTICE: Do not connect or disconnect the communication cable while the drive is powered up or while the drive is in
operation. Failure to comply may cause a static discharge, which will cause the option card to stop working properly.
Cycle power on the drive and option card to reestablish functionality.
■ Network Topology and Connections
The dual RJ45 network ports on the option board act as a switch to allow for flexibility in
cabling topology. For example, a traditional star network topology may be employed by
using a single port on the option board. Alternatively, a daisy-chained approach may be
employed by using both RJ45 ports. This second approach reduces the requirements of
central switch ports.
