118 Control unit of frame R11
DIIL input (XD24:1)
The DIIL input can be selected as the source of, for example, an emergency stop
command or an external event. For more information, see the firmware manual.
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 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 100 meters (328 ft). Avoid unnecessary
loops and running the cable near power cables (such as motor cables).
This diagram shows the wiring of the drive-to-drive link.
Safe torque off (XSTO)
For the drive to start, both connections (OUT1 to IN1 and IN2) must be closed. By default,
the terminal block has jumpers to close the circuit. Remove the jumpers before connecting
an external Safe torque off circuitry to the drive. See chapter The Safe torque off function
on page 199.
Safety functions module connection (X12)
See section Implementing the functions provided by the FSO-xx safety functions module
(option +Q972 or +Q973) on page 82, chapter The Safe torque off function and FSO-12
safety functions module user’s manual (3AXD50000015612 [English]).
