Drive-to-drive link (XD2D)
The drive-to-drive link is a daisy-chained RS-485 transmission line that allows basic
master/follower communication with one master drive and multiple followers.
Set termination activation jumper J3 (see section Jumpers and switches above) next
to this terminal block to the ON position on the drives at the ends of the drive-to-drive
link. On intermediate drives, set the jumper to the OFF position.
Use shielded twisted-pair cable (~100 ohm, for example, PROFIBUS-compatible
cable) for the wiring. For best immunity, high quality cable is recommended. Keep the
cable as short as possible; the maximum length of the link is 50 meters (164 ft). Avoid
unnecessary loops and running the cable near power cables (such as motor cables).
The following diagram shows the wiring of the drive-to-drive link.
DIIL input (XD24:1)
The DIIL input can be selected as the source of, for example, an emergency stop
command or an external event. See the firmware manual for more information.
