3.6.2.5 RJ 45 interface
The RJ45 port located in the front (IP20) or under the connection terminal
cover (IP66) can be used to directly connect the device to communication
modules and fieldbus connections.
The internal RS-485 connection transmits Modbus RTU and CANopen data.

The way the RJ45 interface works is described in the following
manuals:
•
MN040018: “Modbus RTU – Communication manual for DA1,
DC1, DE1 variable frequency drives”
•
MN040019: “CANopen – Communication manual for DA1,
DC1, DE11 variable frequency drives”
•
MN04012009: “PowerXL™ – DX-NET-SWD Interface card
SmartWire-DT for variable frequency drives”
￫
DC1-S… variable frequency drives do not have an internal bus
termination resistor.
Use EASY-NT-R if necessary.
