Ethernet Only Motor Connections
Ethernet is the new method for connecting the motors to other motors and to the node control-
lers using only Ethernet communications as shown in Figure 5-11. This method is only used
with NC-S, NC-12, NC LITE, and NC-E node controllers when using Ethernet motors. See
the MagneMover LITE User Manual for detailed connection information.
NOTE: When using Ethernet to communicate with the motors, other connection schemes
such as multiple chains per path and Ethernet star topologies are possible.
Closed-loop Ethernet connections must be avoided to help prevent network satura-
tion. The simple daisy chain that is shown in Figure 5-11 is typical, but not required.
Figure 5-11: Ethernet Motor Wiring Example
1. Connect a Cat5 Ethernet cable from the switch where the node controller is connected
to the first motor in the Ethernet chain.
2. Connect a Cat5 Ethernet cable from the downstream connection on the motor to the
upstream connection on the next motor in the chain.
3. Continue making motor-to-motor Ethernet connections until the last motor in the path
is reached.
4. Create a MICS file to define the Ethernet motor connections.
