The XD2D connector

The XD2D connector provides an RS-485 connection that can be used for
• basic master/follower communication with one master drive and multiple followers,
• fieldbus control through the embedded fieldbus interface (EFB), or
• drive-to-drive (D2D) communication implemented by application programming.
See the firmware manual of the drive for the related parameter settings.
Enable bus termination on the units at the ends of the drive-to-drive link. Disable bus
termination on the intermediate units.
Use shielded twisted-pair cable with a twisted pair for data and a wire or another pair for
signal ground (nominal impedance 100 to 165 ohm, for example Belden 9842) for the wiring.
For best immunity, ABB recommends high quality cable. Keep the cable as short as possible.
Avoid unnecessary loops and parallel runs near power cables such as motor cables.
The following diagram shows the wiring between control units.
