Technical Specifications Part Number: 3BSE018135R10 Model: CI858K01 Communication Protocol: DriveBus dedicated drive bus protocol Interface: DriveBus field‑bus terminal interface Power Supply: Supplied by rack CEX‑Bus backplane, no external auxiliary power needed Power Consumption: ≤5 VA Operating Temperature: ‑10 ℃ to +50 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Mounting Type: AC800M rack plug‑in module, matched with TP858 baseplate Protection Class: IP20 Certifications: CE, UL, cUL
Functional Features Realizes high‑speed DriveBus communication between AC800M controller and ABB drive equipment. Transmits motor start‑stop, speed reference and other control commands to drive units. Receives drive actual speed, output current, temperature and fault diagnostic information. Supports 1+1 module redundancy for high‑reliability drive control system. Supports module hot‑swap without interrupting other rack‑slot operations. Front‑panel LED indicators show module power‑on, running, bus communication and fault status. Each CI858K01 supports connection of multiple ABB drive units on DriveBus segment. Realizes drive parameter reading‑writing and online fault diagnosis function.
Application Scenarios AC800M system DriveBus drive communication spare‑part replacement. Metallurgy, crane, paper‑making production line multi‑drive coordinated control projects. Industrial production lines adopting large quantity of ABB variable‑frequency drives.
Installation Requirements Fix TP858 baseplate into designated slot of AC800M rack, insert CI858K01 module and lock spring‑clip buckle. Connect DriveBus shielded twisted‑pair bus cable to signal terminals of TP858 baseplate. Install terminal matching resistance at two ends of DriveBus bus‑segment complying with bus specification. Complete cabinet protective earthing following AC800M system grounding specifications. Lay DriveBus signal cables separately from high‑power drive power cables. Reserve heat‑dissipation ventilation space around module slot.
