CI858 3BSE018135R1 ABB DriveBus Interface AC 800M Controller 8 Mbit/s New

DriveBus Interface Overview

The ABB CI858 DriveBus Interface (3BSE018135R1) connects AC 800M controllers to ABB drives and special I/O units. It uses the DriveBus protocol at 8 Mbit/s. This unit powers through the CEX-Bus, so no extra power supply is needed.

• High-speed control: 8 Mbit/s communication with up to 24 drives.
• Hot Swap support: Replace drives without stopping the system.
• Ideal for mills: Designed for rolling mill and paper machine drives.
• 12-month warranty against defects.

Frequently Asked Questions (FAQ)

• How many drives can I connect to one CI858?You can connect up to 24 ABB drives using NDBU branching units. The NDBU creates a star topology and can be chained.
• Do I need external power for the CI858?No. It draws power directly from the AC 800M controller via the CEX-Bus. No 24 V supply is required.
• What is DriveBus used for?DriveBus is designed for high-speed control of ABB drives in rolling mills and paper machines. It ensures precise coordination.
• Can I hot-swap a drive while the system runs?Yes, DriveBus supports Hot Swap. You can replace a faulty drive without stopping the controller or other drives.
• What is the maximum number of CI858 modules per controller?An AC 800M controller accepts a maximum of two CI858 units on the CEX-Bus. This allows up to 48 drives total.

Selection Guide

• Choose CI858 when you need to control multiple ABB drives from an AC 800M in sectional drive applications.
• For each group of drives, order one NDBU branching unit per drive (or per branch).
• Ensure your controller has available CEX-Bus slots (max 2 CI858).
• Not suitable for redundant drive control – use multiple CI858 for separate segments.
• Operating temperature is +5°C minimum; avoid cold starts below this.
