Product Details

CCU-24-H 3AXD50000018771 Product Description

The ABB CCU-24 H (Part No. 3AXD50000018771) is a dedicated Control and Communication Unit engineered for the ACS880 single-drive and multidrives platform. As the central intelligence layer of the ACS880 drive architecture, the CCU-24 H orchestrates real-time motor control algorithms, fieldbus communication, I/O signal management, and system-level diagnostics within a unified, modular hardware framework. Its role extends far beyond a standalone component — it is the architectural keystone that binds the control layer, communication layer, I/O layer, and power layer into a coherent, high-performance automation system.

Designed for demanding industrial environments including manufacturing, energy, petrochemical, water treatment, mining, metallurgy, marine, and process control, the CCU-24 H delivers the signal integrity, redundancy readiness, and long-term maintainability that modern control architectures demand. Every unit supplied by NANKMOS undergoes pre-shipment functional verification and is backed by a 12-Month Warranty, ensuring system-ready deployment from day one.

The CCU-24 H achieves its full potential when deployed within a complete ACS880 automation platform. At the control layer, it interfaces directly with the ACS880 RDCU-02C remote drive control unit and the RMIO-11C motor control and I/O board, forming a tightly coupled control nucleus that manages torque, speed, and flux vector algorithms with sub-millisecond cycle times. The CCU-24 H's dual-port Ethernet backbone enables seamless integration with PROFINET IO controllers and EtherNet/IP PLCs, making it a natural fit for Siemens S7-1500 or Allen-Bradley ControlLogix architectures operating as supervisory control nodes.

At the I/O layer, the CCU-24 H coordinates with the ACS880 AIMA-01 I/O extension module and AITC-01 analog I/O terminal board, expanding the drive's signal acquisition capacity without additional control hardware. This modular I/O architecture supports distributed sensor networks across large process lines, maintaining signal fidelity even in electrically noisy environments typical of heavy industry. The integrated Safe Torque Off (STO) input on the CCU-24 H connects directly to safety relay modules such as the ABB JOKAB SMILE series or Pilz PNOZ safety relays, enabling IEC 62061 SIL 2 / ISO 13849 PLd compliant safety architectures without external safety PLCs.

At the communication layer, the CCU-24 H supports optional fieldbus adapter modules including the FPBA-01 PROFIBUS DP adapter and FENA-21 EtherNet/IP / PROFINET dual-port adapter, enabling the ACS880 drive to participate in both legacy PROFIBUS networks and modern Industrial Ethernet topologies within the same control cabinet. This dual-protocol capability is particularly valuable in brownfield modernization projects where existing PROFIBUS infrastructure must coexist with new PROFINET segments. Industrial managed switches such as the Hirschmann RS20 or Phoenix Contact FL SWITCH series provide the network backbone for deterministic Ethernet communication between the CCU-24 H and the plant DCS or SCADA system.

At the power layer, the CCU-24 H operates from the ACS880's internal APBU-44C auxiliary power buffer unit, which maintains control board power during brief supply interruptions — a critical feature for continuous process applications in petrochemical and water treatment plants where unplanned drive trips carry significant operational cost. The APBU-44C works in conjunction with the ACS880 BCU-12 brake control unit to manage regenerative braking energy, ensuring the DC bus remains within safe operating limits during rapid deceleration cycles.

At the HMI layer, the CCU-24 H communicates with the ACS880 ACS-AP-I assistant control panel via the drive's front panel port, providing local parameter access, fault history review, and real-time signal monitoring without requiring a laptop or engineering workstation. For remote HMI integration, the CCU-24 H's Ethernet port connects to ABB CP600 series HMI panels or third-party SCADA systems via OPC UA or Modbus TCP, enabling plant-wide drive status visualization and alarm management from the control room.

Manufacturing & Packaging Lines: In high-speed packaging and assembly lines, the CCU-24 H enables coordinated multi-axis motion by synchronizing multiple ACS880 drives through a shared PROFINET IO network. Its fast current control loop (typically 62.5 µs) ensures precise torque response during product indexing and conveyor synchronization, reducing mechanical stress on gearboxes and extending drivetrain service life.

Power Generation & Energy: In wind turbine pitch control and hydroelectric generator excitation systems, the CCU-24 H's STO function and redundant encoder interface provide the safety integrity required for grid-connected rotating machinery. Its non-volatile parameter storage ensures that drive configuration survives power cycling without requiring re-commissioning after grid faults.

Petrochemical & Refining: In compressor and pump drive applications within hazardous area control rooms, the CCU-24 H's PROFIBUS DP connectivity integrates the ACS880 drive into Yokogawa CENTUM VP or Honeywell Experion PKS DCS systems, enabling closed-loop flow and pressure control with full drive diagnostics visible at the DCS operator station.

Water & Wastewater Treatment: In pump station automation, the CCU-24 H supports PID process control natively, allowing the ACS880 to regulate pump speed based on pressure transmitter feedback without requiring a separate PLC for the control loop. This reduces panel complexity and lowers the risk of communication latency between the controller and the drive.

Mining & Metallurgy: In conveyor belt and hoist drive systems, the CCU-24 H's load curve monitoring and thermal model functions protect the motor and drive from overload conditions during ore surge events, while its diagnostic data logging capability supports predictive maintenance programs that reduce unplanned downtime in remote mine sites.

Marine & Offshore: In vessel propulsion and thruster control systems, the CCU-24 H's wide operating temperature range and vibration tolerance make it suitable for marine drive cabinets subject to ship motion and salt-laden air ingress, provided the drive enclosure meets the required IP rating for the installation zone.

Q1: Is the CCU-24 H 3AXD50000018771 compatible with all ACS880 drive frame sizes, and can it be retrofitted into existing ACS880 installations? The CCU-24 H is designed for the ACS880 single-drive series and is mechanically and electrically compatible with ACS880 frame sizes R1 through R11. It can be retrofitted into existing ACS880 drives as a direct replacement for the original CCU-24 H unit, provided the drive firmware version supports the hardware revision. NANKMOS recommends verifying the drive firmware version against ABB's compatibility matrix before installation. All units supplied by NANKMOS are pre-shipment tested for electrical functionality and covered by a 12-Month Warranty from the date of delivery.

Q2: What fieldbus options are supported by the CCU-24 H, and how does it integrate into a mixed PROFIBUS / PROFINET control architecture? The CCU-24 H supports native EtherNet/IP and Modbus TCP via its onboard Ethernet port, and extends to PROFIBUS DP and PROFINET IO through optional fieldbus adapter modules (FPBA-01 for PROFIBUS DP; FENA-21 for EtherNet/IP / PROFINET). In mixed-protocol architectures, the CCU-24 H can simultaneously maintain a PROFIBUS DP connection to a legacy DCS and an Ethernet connection to a SCADA system, enabling parallel data paths for control commands and diagnostic monitoring. This Contextual Integration capability makes the CCU-24 H suitable for phased network modernization projects without requiring a full control system replacement.

Q3: What is NANKMOS's inventory availability and lead time for the CCU-24 H 3AXD50000018771, and what does the 12-Month Warranty cover? NANKMOS maintains ready stock of the CCU-24 H 3AXD50000018771 to support urgent maintenance and project procurement requirements. Standard lead time for in-stock units is 3–7 business days for international shipments. The 12-Month Warranty covers manufacturing defects and functional failures under normal operating conditions from the date of delivery. Each unit undergoes pre-shipment functional testing including power-on verification, communication port check, and I/O signal validation before dispatch.
