Product Description

The ABB FDPI-02 is a high-performance Optical DP Diagnostics Interface designed for the ACS880 and DCS880 industrial drive series. It acts as an adapter that converts the drive’s internal communication (via the fiber optic link) to a standard PROFIBUS DP interface, while providing advanced diagnostic capabilities.

Product Parameters

The FDPI-02 is specifically engineered to integrate ABB’s high-power drives into Profibus networks with enhanced reliability.

Key Product Advantages

• Optical Isolation: By using fiber optics (DDCS) between the drive and the interface, it eliminates ground loops and protects the control system from high-voltage transients and electromagnetic interference (EMI).

• Advanced Diagnostics: Unlike standard adapters, the “Diagnostics” version (FDPI) provides detailed information about the Profibus network quality and slave status directly to the drive’s control board.

• Plug-and-Play Integration: The drive’s firmware automatically recognizes the FDPI-02, allowing for easy configuration of parameters like Node Address and PPO Types via the drive’s keypad or PC tools (Drive Composer).

• Deterministic Communication: Ensures high-speed, real-time data exchange for critical control loops in high-performance motor applications.

• Legacy Compatibility: Allows modern ACS880 drives to replace older ACS800 units in existing Profibus-based plant architectures without changing the PLC hardware.

Product Applications

• Variable Speed Drives (VSD): Used in any industrial environment where an ACS880 drive must communicate with a Siemens, ABB, or third-party PLC via Profibus DP.

• Heavy Industry: Ideal for Steel Mills and Mining where electrical noise is high and fiber optic isolation is a safety requirement.

• Pulp and Paper: Coordinating multiple drives in a sectional drive system where precise synchronization is required over a fieldbus.

• Retrofit Projects: Upgrading older drive systems to the ACS880 platform while maintaining the existing fieldbus network.

Important Usage Notes (Precautions)

• Fiber Optic Handling: The DDCS fiber optic cables are fragile. Ensure the minimum bending radius is maintained (typically 35 mm) to avoid signal attenuation or glass breakage.

• Profibus Termination: The FDPI-02 does not have a built-in termination resistor. The standard 9-pin D-sub connector used must have a termination switch, which must be set to “ON” if the module is the last device on the Profibus segment.

• Addressing: The Profibus station address is usually set via drive parameters (e.g., Parameter Group 51). Ensure there are no address conflicts on the network.

• Power Supply: Ensure the drive’s control unit (ZCU/BCU) is powered correctly, as the FDPI-02 typically draws power from the drive’s internal bus.

Typical Wiring Configuration

1. Connect the Optical Transmit (Tx) and Receive (Rx) cables from the FDPI-02 to the drive’s DDCS channel (usually Channel 0).

2. Plug the standard Profibus 9-pin cable into the D-sub connector.

3. Configure the drive parameters to enable Fieldbus Adapter A or B.
