Stable Performance Brand New Servo Drive Converter Rexroth R911326039 HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW

The REXROTH R911326039 HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW is a compact servo drive converter from the Rexroth HCS01 / IndraDrive Cs product family. It is designed for industrial machines that need precise single-axis servo control in a compact electrical cabinet layout. This model is suitable for motion-control systems where accurate positioning, repeatable speed control, stable torque response, and reliable communication with the machine controller are required.

The full model code HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW should be kept complete in all technical and commercial documents. The order number R911326039 is equally important because purchasing teams, maintenance departments, and industrial spare-parts suppliers often search by order number. For a product page, quotation sheet, packing list, or export invoice, the safest description is REXROTH R911326039 HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW Compact Servo Drive Converter.

Product Identification

The estimated product net weight is approximately 1.3 kg. This weight is a practical reference for product listings, warehouse records, export preparation, and preliminary freight calculation. The actual packed weight may be higher after adding the carton, anti-static bag, foam protection, paper documents, labels, and other packing materials. If the drive is shipped as refurbished stock, used tested stock, or new surplus stock, packaging may not be identical to the original factory carton. For this reason, the final gross weight should always be confirmed by weighing the packed unit before shipment.

The REXROTH R911326039 compact converter is intended for servo-axis applications. It is different from a simple variable-frequency drive because it is normally used in closed-loop motion-control systems. In operation, the drive receives command values from the automation controller, processes feedback from the motor encoder, and regulates motor current to control the axis. This allows the machine to achieve controlled position, speed, and torque behavior according to the programmed motion sequence.

Typical application areas include packaging machines, printing equipment, labeling machines, handling systems, feeding units, small rotary tables, inspection machines, assembly equipment, textile machinery, testing systems, and compact production modules. The W0003 current class makes this model more suitable for smaller servo axes and auxiliary motion sections rather than high-power main drive tasks. It is useful where a machine needs accurate movement but does not require a large converter.

Technical Overview

One important feature of the HCS01 compact drive format is its suitability for machines with limited cabinet space. Modern automated equipment often uses several small servo axes instead of one large mechanical drive train. A compact drive converter allows the system designer to organize each axis separately and maintain a clear connection between drive, motor, parameter set, and machine function. This structure is useful for troubleshooting because each motion section can be diagnosed independently.

The ET code in the model number should be treated as a critical communication identifier. It relates to the drive’s communication configuration and should be checked against the machine controller. The EC code is also important because it relates to encoder interface configuration. The three NN positions indicate that this version does not include certain additional option configurations in those positions. However, this does not mean that it is automatically interchangeable with every other HCS01 W0003 drive. The complete suffix must still be matched.

For maintenance replacement, the original nameplate should be photographed and compared line by line. The proposed replacement should match R911326039 or the complete model HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW. If the machine documentation lists a different order number but a similar model code, the firmware and option configuration should be checked before accepting it as a replacement. In Rexroth drive systems, hardware code, firmware, parameter set, motor encoder type, and controller communication settings all affect successful commissioning.

Replacement and Commissioning Checklist

The installation environment should be a protected electrical cabinet with suitable ventilation and grounding. Drive installation should follow machine documentation and applicable electrical safety practices. Power cables should be separated from signal and encoder cables where possible. Proper shielding and grounding are important because motion-control drives can be sensitive to electrical noise. Poor wiring can lead to encoder errors, communication faults, nuisance alarms, or unstable axis behavior.

For online product content, this model should be described accurately and conservatively. A good searchable product name is REXROTH R911326039 HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW Compact Servo Drive Converter. This phrase includes the brand, order number, complete model, and product category. It is suitable for Google search indexing because industrial buyers usually search exact codes instead of broad marketing terms.

Important search phrases for this product include R911326039, HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW, HCS01 compact converter, IndraDrive Cs servo drive, compact servo drive converter, single-axis servo drive, industrial automation drive, and motion control spare part. These keywords should be placed naturally in product descriptions, page headings, and technical tables. They should not be repeated excessively, because keyword stuffing reduces page quality and may weaken search performance.

The value of this drive in an industrial spare-parts program is mainly based on exact compatibility. Many factories use compact servo drives in critical sections of production equipment. If one axis fails, downtime can stop the complete machine. Having the correct HCS01 model available can reduce repair time, but only if the replacement matches the actual machine configuration. An incorrect suffix, wrong firmware, or missing parameter backup can delay recovery even when the drive looks physically identical.

For B2B supply, the product condition should be stated separately from the technical identity. If the unit is brand new, new surplus, used tested, or refurbished, that condition should be listed clearly in the quotation. The model code must not be changed to describe the condition. The same applies to warranty, lead time, and packaging method. These are commercial terms and should remain separate from the Rexroth order number and type code.

In summary, the REXROTH R911326039 HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW is a compact single-axis servo drive converter for precise motion-control applications in industrial automation systems. It belongs to the HCS01 / IndraDrive Cs compact converter family and is suitable for cabinet-mounted servo-axis control in packaging, handling, printing, assembly, and similar equipment. The estimated net product weight is approximately 1.3 kg, while the final shipping weight should be verified after packaging. For reliable sourcing and replacement, both the order number R911326039 and the full model code HCS01.1E-W0003-A-02-B-ET-EC-NN-NN-NN-FW should always be used together.
