RS-422 and Ethernet Motor Connections
This method mixes the traditional RS-422 connection scheme for connecting the motors to
other motors and to the node controllers and the new Ethernet connection scheme as shown in
. This method is only used with NC-S, NC-12, and NC LITE node controllers
when combining RS-422 motors and Ethernet motors in the same transport system. See the
MagneMover LITE User Manual
for detailed connection information.
Figure 5-12: RS-422 and Ethernet Motor Wiring Example
1.
Connect the motors that use RS-422 communications as described in
2.
Connect a Cat5 Ethernet cable from the switch where the node controller is connected
to the first motor in the Ethernet chain.
3.
Connect a Cat5 Ethernet cable from the downstream connection on the motor to the
upstream connection on the next motor in the chain.
4.
Continue making motor-to-motor Ethernet connections until the last motor in the path
is reached.
5.
Create a MICS file to define the Ethernet motor connections.
