Installing Motor and RS-422 Motor Controller Communication Cables
See Figure 4-9 for the connection locations on the QSHT motors and Figure 4-16 and
Figure 4-17 for the connection locations on the QSMC motor controllers. See the Node Con-
troller Hardware User Manual, MMI-UM013, for the communication connection locations
on the node controllers. See Figure 5-5 and Figure 5-6 for simplified diagrams of the wiring
and Figure 5-7 for a detailed example.
When connecting the motor controllers to the node controllers, both ends of a path do not need
to connect to the same node controller. However, all connections to the motor controllers for
