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"
￫
DB1 variable frequency drives have no internal bus termination
resistor.
Use EASY-NT-R if necessary.
