Electrical installation61Drive-to-drive link (X5)The drive-to-drive link is a daisy-chained RS-485 transmission line that allows basicmaster/follower communication with one master drive and multiple followers.Termination activation jumper J3 (see section Jumpers above) next to this terminalblock must be set to the ON position on the drives at the ends of the drive-to-drivelink. On intermediate drives, the jumper must be set to the OFF position.Shielded twisted-pair cable (~100 ohm, e.g. PROFIBUS-compatible cable) must beused for the wiring. For best immunity, high quality cable is recommended. The cableshould be kept as short as possible; the maximum length of the link is 50 metres(164 ft). Unnecessary loops and running the cable near power cables (such as motorcables) must be avoided. The cable shields are to be grounded to the control cableclamp plate on the drive as shown on page 62.The following diagram shows the wiring of the drive-to-drive link.Safe Torque Off (X6)For the drive to start, both connections (OUT1 to IN1, and OUT2 to IN2) must beclosed. By default, the terminal block has jumpers to close the circuit. Remove thejumpers before connecting an external Safe Torque Off circuitry to the drive.
