Using Both RS-422 and Ethernet Motors
Transport systems can easily combine both RS-422 and Ethernet drives. Drive types are typi-
cally combined in a transport system when new motors with drives that use Ethernet (QSHT
5700 inverters) are added to an existing RS-422 system. When adding new drives using Ether-
net communication, it is recommended that they be added as one path to simplify configura-
tion. Nodes are needed at the junction of RS-422 and Ethernet paths as shown in
to make the transition between motor types. Additionally, all
Ethernet motors and their location on the path must be defined in the MICS file (see
Straight Paths

NOTICE
When combining QSMC drives using RS-422 communica-
tion and QSHT 5700 drives using Ethernet communication,
the power requirements for the drives are different and
require different power buses as shown in
.
