ABB TEPI1-R1D 1KHW002601R0001 Migration-Ready AC Drive Control

Overview

ABB TEPI1-R1D 1KHW002601R0001 Migration-Ready AC Drive Control Board for Legacy Control Systems

The ABB TEPI1-R1D (part number 1KHW002601R0001) is a migration-ready AC drive control board engineered for the ACS800 series variable frequency drive platform. As legacy ACS800 installations approach end-of-support milestones, plant engineers and maintenance teams increasingly rely on verified replacement boards like the TEPI1-R1D to extend operational life, avoid unplanned downtime, and defer full drive replacement capital expenditure. This board serves as a direct functional replacement for the discontinued 1KHW002602R0001, maintaining full compatibility with the ACS800 control architecture, firmware interface, and I/O signal mapping.

Each unit is pre-shipment tested under load conditions to validate gate drive signals, feedback loop integrity, and communication bus response before dispatch. Stock is maintained across multiple warehouse locations to support emergency replacement orders with rapid global dispatch. All units are covered by a support terms confirmed by quotation from the date of shipment.

Retrofit Planning for Existing Automation Systems

Replacing the TEPI1-R1D within an active ACS800 installation requires a structured retrofit plan that accounts for the broader control cabinet ecosystem. Before initiating the board swap, engineers should audit the NAMC-11 or NAMC-03 main control board to confirm firmware version compatibility, as the TEPI1-R1D interfaces directly with the main control layer for gate pulse generation and feedback processing. If the drive is integrated into a DCS or SCADA network via a PROFIBUS-DP fieldbus adapter such as the RPBA-01, the fieldbus node address and GSD file configuration must be documented prior to shutdown to ensure seamless re-commissioning.

For installations using the RDCO-03 DDCS communication module to link the ACS800 into a multi-drive system or to an AC800M controller, verify that the optical fiber connections and node addressing remain intact after the board replacement. The RDCO-03 configuration is stored in the main control board, not the TEPI1-R1D, so communication parameters are typically preserved across the swap.

Terminal wiring on the ACS800 I/O extension module — such as the RAIO-01 analog I/O extension — should be photographed and documented before any work begins. While the TEPI1-R1D does not directly interface with the RAIO-01, disruption to the control cabinet during board removal can inadvertently loosen terminal connections on adjacent modules. Similarly, if the installation includes an AINT-02 or AINT-14 inverter control interface board in a multi-drive cabinet, confirm that the shared DC bus configuration and inverter enable signals are correctly isolated before removing the TEPI1-R1D from service.

HMI panels connected to the ACS800 via the CDP312R control panel interface or via a serial link to a third-party SCADA system should be placed in manual override or local control mode during the replacement window to prevent nuisance alarms and to protect process continuity. After reinstallation, restore the drive to remote control mode and verify that all parameter sets — including motor nameplate data, speed references, and protection thresholds — are correctly loaded, either from a backup parameter file or from the CDP312R panel memory.

Downtime Control During System Migration

Minimizing production downtime during an ACS800 TEPI1-R1D replacement begins with pre-work preparation. Before the maintenance window opens, download a full parameter backup from the drive using the DriveWindow Light PC tool or the CDP312R panel. This backup preserves motor identification data, PID tuning parameters, speed ramp settings, and all fieldbus configuration — ensuring that post-replacement commissioning is reduced to parameter restore and a brief ID run rather than a full re-commissioning cycle.

Where process criticality demands zero-interruption operation, consider staging a pre-configured spare ACS800 drive unit with the replacement TEPI1-R1D already installed and parameters pre-loaded. This hot-swap approach reduces the active maintenance window to the time required for cable transfer and drive enable, typically under 30 minutes for a prepared team.

For installations where a full drive swap is not feasible, the board-level replacement of the TEPI1-R1D can typically be completed within a 2–4 hour planned maintenance window, including parameter restore, motor ID run, and functional verification under no-load and partial-load conditions. Ensure that the replacement board is at ambient temperature before installation to avoid condensation on the PCB surface, and confirm that all ESD precautions are observed during handling.

After reinstallation, perform a controlled ramp-up sequence: start the drive in local control mode at reduced speed reference, verify current feedback and speed feedback signals on the drive display, then transfer to remote control and confirm that the DCS or SCADA system receives correct status signals before returning the process to automatic mode. This staged verification sequence protects the original program logic and maintains field control continuity throughout the migration.

Retrofit Support FAQ

Q: Is the ABB TEPI1-R1D 1KHW002601R0001 a direct replacement for the 1KHW002602R0001?
A: Yes. The TEPI1-R1D (1KHW002601R0001) is the verified functional replacement for the discontinued 1KHW002602R0001. It maintains the same backplane connector layout, gate drive interface, and I/O signal assignments within the ACS800 platform. No hardware modification to the drive chassis is required.

Q: What commissioning steps are required after installing the replacement board?
A: After physical installation, restore the drive parameter set from a pre-saved backup file. If motor identification data was stored on the original board and cannot be recovered, perform a new motor ID run (stationary or rotating, depending on process constraints). Verify all analog and digital I/O signals, confirm fieldbus communication status, and perform a controlled no-load test run before returning the drive to production service.

Q: How is the board tested before shipment?
A: Every TEPI1-R1D unit undergoes a full pre-shipment functional test that validates gate drive output signals, power supply rail integrity, communication bus response, and feedback signal processing. Test records are retained for traceability. Units that do not pass all test criteria are not dispatched.

Q: What support terms and stock availability can I expect?
A: All units are covered by a support terms confirmed by quotation from the date of shipment, covering manufacturing defects and functional failures under normal operating conditions. Stock is maintained across multiple locations to support urgent replacement requirements, with rapid global dispatch available for emergency orders. Contact our team to confirm current lead time and regional stock availability.
