The external control unit is delivered in a cardboard box inside the main drive module package. Unpack the external control unit package. Make sure that it contains these items:
• ZCU-12 control unit
• mounting template. The mounting template contains a mounting pattern for a ZCU-12 control unit on one side and a mounting pattern for a CCU-24 control unit on the other side.
External power supply for the control unit (XPOW) The control unit is powered from a 24 V DC, 2 A supply through terminal block XPOW. Using an external supply is recommended, if:
• the control unit needs to be kept operational during input power breaks, for example, because of continuous fieldbus communication
• immediate restart is needed after a power break (that is, no control unit power-up delay is allowed).
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 a high-quality shielded twisted-pair cable for the wiring,fro exmple, Belden 9842. The nominal impedance of the cable should be 100…165 ohm. You can use one pair for the data wiring and another pair or a wire for the grounding. Avoid unnecessary loops and parallel runs near power cables. The following diagram shows the wiring between control units.
