XD2D: Drive-to-drive link
The drive-to-drive link is a daisy-chained RS-485 transmission line that allows basic master-follower communication with
one master and multiple followers. It is also used for the embedded fieldbus.
Set the termination switches J3 (see Jumpers and switches
) next to terminal block XD2D to terminated ( ) at the two
physical ends of the drive-to-drive link. All intermediate switches have to be set to not terminated ( ).
