ABB 1KHW001356R0001 P4RX Replacement for ACS Drive

Product Overview

ABB 1KHW001356R0001 P4RX Replacement & Upgrade Solution for ACS Drive Series

When your ABB ACS drive system demands a reliable EMC filter replacement, the ABB 1KHW001356R0001 P4RX delivers a seamless, drop-in upgrade path that preserves your existing wiring infrastructure, cabinet layout, and drive communication architecture. Designed as a direct replacement for legacy RX-type EMC filter modules used across the ACS355, ACS580, and ACS880 drive families, this module eliminates the need for costly panel redesigns or software re-commissioning.

Industrial facilities operating aging ACS drive cabinets frequently encounter discontinued or end-of-life EMC filter modules that compromise CE compliance and electromagnetic compatibility. The 1KHW001356R0001 P4RX restores full IEC/EN 61800-3 Category C2 compliance, suppressing conducted emissions at the drive input and protecting upstream PLC systems, I/O modules, and field instrumentation from high-frequency interference generated by the inverter stage.

This module mounts directly to the drive’s standard DIN rail or panel-mount bracket without modification. Input and output terminal assignments mirror the original P4RX footprint, allowing maintenance teams to complete a like-for-like swap during a planned shutdown window — typically under 30 minutes for a trained technician. No firmware changes, no parameter re-entry, and no changes to the PROFIBUS DP or PROFINET communication configuration are required.

In multi-drive installations where an ACS880 multidrives cabinet houses several inverter units sharing a common DC bus, replacing a failed EMC filter on one drive section no longer requires taking the entire cabinet offline. The 1KHW001356R0001 P4RX is rated for the same input voltage and current class as the original, ensuring that adjacent drive modules — including the ACS880-104 inverter units and associated BCU-12 brake chopper units — continue operating without interruption.

For retrofit projects migrating from older ACS600 or ACS800 drive platforms to the current ACS880 generation, the P4RX filter module is a critical first step. Engineers replacing legacy AINT-02C interface boards, RDCO-03 communication adapters, or RMIO-11C control boards will find that the 1KHW001356R0001 P4RX integrates cleanly into the new drive’s power input stage, maintaining the same cable entry points and grounding scheme used in the original installation. This is particularly valuable in food processing, water treatment, and HVAC applications where cable routing through cable trays and conduit is fixed and cannot be easily rerouted.

Power supply compatibility is maintained across the standard 380–480 V AC, 50/60 Hz industrial supply range. The module’s internal capacitor and inductor network is pre-tuned to the ACS drive’s switching frequency profile, eliminating the need for external line reactors in most standard installation scenarios. Where a du/dt filter or sine filter is already installed upstream, the 1KHW001356R0001 P4RX operates in series without derating.

Procurement teams sourcing this module as a critical spare should note that the 1KHW001356R0001 P4RX is stocked and available for immediate dispatch from our Xiamen warehouse. Each unit undergoes pre-shipment functional verification including insulation resistance testing and terminal continuity checks. Units are shipped in original or equivalent protective packaging with full traceability documentation.

Compatibility Comparison Table

Seamless Upgrade Solutions

A successful ACS drive EMC filter replacement rarely happens in isolation. During the same maintenance window, engineering teams commonly address adjacent components that share the same service interval or that have been flagged during predictive maintenance inspections.

In ACS880 multidrives cabinets, the ACS880-104 inverter module and its associated BCU-12 brake chopper unit are frequently serviced alongside the EMC filter, as all three components share the same DC bus and are subject to similar thermal and electrical stress cycles. Replacing the 1KHW001356R0001 P4RX at the same time as a scheduled BCU-12 inspection eliminates a second planned outage within the same quarter.

For installations that rely on fieldbus communication, the FPBA-01 PROFIBUS DP adapter module and FENA-21 Ethernet adapter are common companion replacements. These communication modules plug into the drive’s option slot and are unaffected by the EMC filter swap, but their firmware versions should be verified against the drive’s current software baseline during the same service visit.

Where the drive feeds a motor through a long cable run exceeding 50 meters, a du/dt output filter or FOCH sine filter is typically installed in series with the drive output. These output-side filters work in conjunction with the 1KHW001356R0001 P4RX input EMC filter to provide full-spectrum conducted and radiated emission control across the complete drive-motor system.

Control wiring integrity should also be verified during the filter replacement. The RMIO-11C control board and its associated AIMA-01 analog I/O extension module provide the signal interface between the drive and the plant DCS or PLC. Ensuring that shielded control cables are correctly terminated at the drive’s PE terminal block — which is physically adjacent to the EMC filter mounting position — prevents ground loop issues that can cause erratic speed reference signals after recommissioning.

For sites migrating from ACS600 or ACS800 platforms, the AINT-02C interface board and RDCO-03 DDCS communication adapter from the legacy system are not forward-compatible with ACS880 hardware. However, the physical cabinet space freed by removing these older boards can be repurposed to accommodate the new drive’s ZCU-14 control unit and its associated I/O terminal blocks, making the 1KHW001356R0001 P4RX a natural starting point for a phased cabinet modernization program.

Retrofit Guidance FAQ

Q: Can I replace the 1KHW001356R0001 P4RX without rewiring the input terminals?
A: Yes. The P4RX replacement uses the same terminal layout and cable entry positions as the original module. Existing cable lugs and ferrules can be reused provided they are within their rated torque specification. Verify terminal tightness to the manufacturer’s specified Nm value after reinstallation.

Q: Will replacing the EMC filter affect my PROFIBUS DP or PROFINET configuration?
A: No. The 1KHW001356R0001 P4RX is a passive power-stage component with no connection to the drive’s communication bus. PROFIBUS node addresses, baud rate settings, and PROFINET device names are stored in the drive’s ZCU control unit and are unaffected by filter replacement.

Q: Is the P4RX compatible with both ACS580 and ACS880 drive frames?
A: The 1KHW001356R0001 P4RX is rated for the P4RX frame size class. Verify your drive’s frame size designation (R1–R11 for ACS880, R1–R9 for ACS580) against the filter’s current rating before installation. Contact our technical team with your drive’s full type code for frame-size confirmation.

Q: What is the physical installation space requirement?
A: The module dimensions match the original P4RX footprint. No additional panel space is required for a like-for-like replacement. For new installations in a retrofit cabinet, allow standard clearance above and below the module for airflow as specified in ABB’s drive installation manual.

Q: Can this module be used with a VFD that drives a pump or fan in a water treatment application?
A: Yes. The 1KHW001356R0001 P4RX is suitable for pump, fan, compressor, and conveyor drive applications. Its C2 EMC classification is appropriate for industrial environments where the drive is connected to a public low-voltage supply through a dedicated transformer.

Q: How do I verify the module is functioning correctly after installation?
A: After installation, perform an insulation resistance test on the input supply cables with the filter connected. Then power up the drive and verify that no EMC-related fault codes (e.g., earth fault F0022 on ACS880) are present. Measure input current balance across all three phases to confirm the filter’s inductor network is intact.
