Technical Introduction
The ABB CDP312R is the operator interface used for local control, monitoring, and parameter access on ABB drive systems.
ABB documentation identifies the CDP312R as the control panel for ACS800 drives. It provides local Start/Stop, direction, reset, reference adjustment, parameter configuration, and drive-status monitoring. The panel communicates with the drive through ABB’s Panel Link, using a Modbus-based communication bus; ABB documentation also states that a CDP312-type panel can communicate with multiple drives on the same bus, with each station assigned a unique ID.
The panel has a 4-line, 20-character LCD and dedicated operating modes for actual signals, parameters, functions, and drive selection.
Best Suited For
- ABB ACS800 drive maintenance

ABB CDP312R
ABB documentation confirms the CDP312R as the user interface for ACS800 drives, with local operating and parameter-setting functions.
Field Engineer’s Tech Notes
- Check the drive firmware/application before assuming compatibility. The CDP312 family was used across different ABB drive generations, but firmware compatibility matters. For ACS600 applications, ABB documentation specifically notes that the CDP312 does not communicate with application-program versions 3.x or earlier.
- Verify the Panel Link configuration. If multiple drives share the communication bus, confirm the drive ID before commissioning. ABB documentation describes unique station IDs for drives connected to the panel link. A replacement panel should also be checked for correct identification and communication behavior before being placed into service.
Adaptive QA & Testing Protocol
For a CDP312R, QA focuses on the operator interface and its communication with the compatible ABB drive platform.
Inspection includes the LCD, keypad membrane, housing, connector, mounting features, and identification label. Where a compatible ABB drive test setup is available, the panel is connected and checked for initialization, display operation, key response, drive identification, parameter-menu access, actual-value display, and local control functions.
For applicable systems, the Panel Link communication path is also checked to confirm that the panel establishes communication with the drive.
Test reports, inspection photographs, and available test videos can be provided upon request.
Buyer’s FAQ
Is the ABB a replacement for an existing ACS800 control panel?
Yes, the is the documented control-panel type for ABB drives. Confirm the exact drive model, panel version, and application firmware before ordering.
Is the new or refurbished?
Condition depends on available inventory. New surplus, new old stock, and refurbished panels may be available. The exact condition and test status should be confirmed with the quotation.
Can the panel be tested before shipment?
Yes. When a compatible ABB drive test setup is available, the panel can be checked for display operation, keypad response, drive identification, parameter access, and Panel Link communication.
What information should I provide when requesting a replacement?
Provide the existing label photograph, ABB drive model, firmware/application version if available, quantity, required condition, and destination. This helps prevent an incorrect panel or incompatible revision from being supplied.
