9.2.1 COM Port
The electrical connection between the master and the slaves is established
with RJ45 cables. If you use multiple slaves, they will need to be connected
in parallel by using RJ45 cables and DX-SPL-RJ45-2SL1PL splitters. Please
note that the stub lines should be as short as possible.
The DC1 variable frequency drive's built-in RJ45 port supports the CANopen
protocol, making it possible to establish a direct network connection without
the need for an additional interface module. A bus termination resistor with a
resistance of 120 needs to be connected at each physical end (last
module) of the network cable in order to prevent signal reflections and the
associated transfer errors.
