New Original Genuine Servo Drive Converter Rexroth R911393600 HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW for Industrial Machinery

The REXROTH R911393600 HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW is a compact servo drive converter from the Rexroth IndraDrive Cs / HCS01 series. It is designed for precise single-axis motion control in industrial automation equipment where cabinet space, axis stability, communication reliability, and service replacement accuracy are important. The HCS01 product family is widely listed as an IndraDrive compact converter, and comparable official Rexroth store references for the HCS01.1E-W0003 class identify this size as a compact converter with a listed weight of 1.3 kg.

This model is suitable for automation systems that require controlled servo movement rather than basic motor speed regulation. In a typical machine, the drive receives motion commands from the controller, processes encoder feedback, and regulates motor current to control position, speed, and torque. The full model code HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW should be used exactly as written, because each suffix position represents a specific configuration. The order number R911393600 should also be included in purchase records, spare-parts lists, quotation documents, export invoices, and product listings.

Basic Product Information

The product weight is approximately 1.3 kg. This value is suitable for website product pages, warehouse reference, preliminary freight calculation, and product comparison within the HCS01 W0003 compact drive class. For commercial shipment, the final gross weight should be measured after packing, because carton material, foam protection, manuals, labels, and additional accessories can increase the actual shipping weight. If the unit is supplied as refurbished or used stock, packaging may also differ from factory packaging.

The REXROTH R911393600 compact converter is commonly used in machine automation applications where one servo axis must be controlled accurately and independently. Typical applications include packaging machines, labeling equipment, feeding axes, printing machinery, small handling systems, indexing mechanisms, assembly stations, inspection machines, textile equipment, and automated production modules. The compact HCS01 structure makes it useful for machines with limited cabinet space or for systems where multiple small drives are installed side by side.

Unlike a general-purpose frequency inverter, this HCS01 compact converter is intended for servo drive applications. Its main function is not merely changing motor speed; it is used to support controlled motion behavior based on feedback and drive parameters. When matched with a compatible Rexroth servo motor and correct firmware, the drive can support stable axis response, repeatable positioning, smooth acceleration and deceleration, and predictable machine operation. For this reason, it is often found in production equipment where downtime, positioning error, or axis instability can directly affect output quality.

Technical Overview

The W0003 section indicates a small compact current class. This makes the unit appropriate for light servo-axis duties rather than high-power drive applications. It may be used for auxiliary machine movements, positioning slides, light feeding mechanisms, small rotary axes, sensor-positioning mechanisms, and other controlled movement sections in automated equipment. The benefit of this configuration is that the machine builder can use a compact, application-specific drive instead of installing an oversized converter.

The ET section of the model code should be treated as a critical communication-related identifier. The EC section should also be checked because it relates to encoder interface configuration. The L3 suffix is another important code position and should not be ignored during replacement selection. Two HCS01 drives may share the same W0003 power class but still differ in communication interface, encoder interface, safety function, firmware compatibility, or panel behavior. Therefore, selecting a replacement only by the first part of the model code is risky.

For maintenance replacement, engineers should compare the complete type code from the existing machine against the proposed spare part. The exact order number R911393600 should be verified if it appears in the machine documentation or spare-parts list. If only the model code is available, the complete suffix string must still be checked before shipment. A small mismatch in the option section can cause commissioning problems, communication failure, encoder incompatibility, or parameter loading errors.

Replacement and Commissioning Checklist

The installation environment should be a protected electrical cabinet with suitable ventilation, grounding, and EMC-compliant wiring. Power cables, motor cables, encoder cables, and communication cables should be routed according to the machine builder’s electrical design. Poor grounding or cable separation can cause noise-related faults, unstable feedback, or intermittent communication errors. For used or refurbished units, the terminals and connectors should be inspected carefully before installation.

For inventory management, the safest product description is REXROTH R911393600 HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW Compact Servo Drive Converter. This wording includes the brand, order number, full model code, product family, and product type. It is also practical for Google search indexing because industrial buyers often search using the exact order number or the full Rexroth type code. The full model should not be shortened in the main title, because shortening can reduce search accuracy and may lead to inquiries for incompatible versions.

This product page can naturally target search phrases such as R911393600, HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW, HCS01 compact converter, IndraDrive Cs servo drive, single-axis servo drive converter, industrial automation servo drive, and Rexroth motion control spare part. These terms describe the product accurately without claiming universal compatibility. For B2B industrial sales, accurate identification is more valuable than exaggerated marketing language.

In actual service use, the REXROTH R911393600 drive can help reduce downtime when it is selected as a correct like-for-like replacement. However, it should not be treated as automatically interchangeable with all HCS01 W0003 drives. The complete hardware configuration, firmware, project parameters, encoder feedback, and controller communication setup must be reviewed before installation. If the drive is supplied for urgent machine repair, it is recommended to provide clear photographs of the nameplate, connector area, and packaging label to the customer before shipment.

In summary, the REXROTH R911393600 HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW is a compact single-axis servo drive converter for industrial automation systems requiring accurate and stable motion control. It belongs to the HCS01 / IndraDrive Cs compact converter family and is suitable for cabinet-mounted servo axis applications. The product weight is approximately 1.3 kg, while final gross weight should be confirmed after packaging. For accurate sourcing, replacement, and technical communication, both R911393600 and HCS01.1E-W0003-A-02-B-ET-EC-NN-L3-NN-AW should always be used together.
