Product Net Weight
1.3 kg
Gross Weight Note
3.0kg
The estimated net weight of the REXROTH R911338561 is approximately 1.3 kg. This value is suitable for product descriptions, warehouse reference, quotation preparation, and preliminary freight estimation. The actual shipping weight may be higher after adding the carton, foam protection, anti-static packaging, labels, documentation, and any additional accessories. For export documents and international freight booking, the final gross weight should be measured after packing instead of relying only on the estimated net weight.
The REXROTH R911338561 is a servo drive converter, not a simple motor starter or ordinary frequency inverter. Its purpose is to control a servo motor in a closed-loop motion system. In a typical machine, the drive receives commands from the controller, reads feedback from the encoder, and regulates the motor output according to the configured parameters and firmware. This allows the machine axis to perform controlled positioning, speed regulation, torque response, acceleration, deceleration, and synchronized motion.
This model is suitable for packaging machinery, labeling equipment, printing machines, feeding axes, compact handling systems, automated assembly machines, inspection stations, textile equipment, small indexing mechanisms, and test machines. The W0003 class makes it suitable for smaller servo axes and auxiliary motion sections rather than large high-power drive applications. It is often selected where space-saving design, precise axis control, and dependable servo performance are more important than high output power.

A major advantage of the HCS01 compact platform is its ability to support machine designs with multiple small servo axes inside a limited control-cabinet space. Modern machines often use one drive for each controlled motion section. This layout allows the machine builder to assign a dedicated drive to a feed axis, label axis, positioning slide, inspection movement, or small rotary table. The result is a clearer relationship between the controller axis, motor, feedback device, parameter file, and mechanical function.
The ET section in the model code is a communication-related identifier and should be checked against the machine controller system. The EC section relates to encoder interface configuration and must match the connected servo motor feedback system. The PB section is a specific option position, while the L3 section may indicate an important functional or safety-related configuration. These suffix positions should never be ignored. A visually similar HCS01.1E-W0003 drive may not be directly interchangeable if these option codes are different.

For maintenance replacement, the full type code should be compared with the original drive label line by line. Selecting a replacement only by the first part of the model, such as HCS01.1E-W0003, is not sufficient. Similar compact converters may differ in communication interface, encoder feedback support, safety function, control panel arrangement, firmware package, or parameter compatibility. A small suffix difference can result in controller communication errors, motor feedback faults, rejected parameter files, or unsuccessful commissioning.
Before replacing the drive, the original parameters should be backed up if the old unit can still communicate. The engineer should also record the motor type, encoder type, brake configuration, controller network settings, address information, firmware version, and any axis-specific tuning parameters. After installation, the replacement drive should be commissioned according to the machine builder’s electrical documentation and the existing Rexroth project data. This process helps prevent wrong axis direction, unexpected motion, brake release problems, encoder alarms, and safety-related faults.

The installation environment should be a properly protected electrical cabinet. The cabinet should provide suitable ventilation, grounding, and protection against dust, oil mist, moisture, vibration, and accidental contact. Power wiring, motor wiring, encoder wiring, and communication wiring should follow good industrial EMC practice. Signal cables should be separated from high-power cables where possible. Poor grounding or incorrect shielding can lead to unstable encoder feedback, communication interruptions, or difficult-to-trace drive alarms.
For online publishing and Google search visibility, this product should be described with exact technical wording. Industrial buyers often search by the order number R911338561 or by the complete type code HCS01.1E-W0003-A-02-B-ET-EC-PB-L3-NN-FW. The full code should appear in the title, product table, and body text. It should not be shortened, split incorrectly, or rewritten in a way that changes the original identification. At the same time, the content should avoid excessive repetition because search engines can treat keyword stuffing as low-quality content.
Useful search phrases for this product include REXROTH R911338561, HCS01.1E-W0003-A-02-B-ET-EC-PB-L3-NN-FW, HCS01 compact servo drive, IndraDrive Cs compact converter, single-axis servo drive converter, industrial automation drive, motion control spare part, and cabinet-mounted servo drive. These terms describe the product clearly and help professional buyers find the correct component when searching for Rexroth drive replacements.
From a spare-parts management perspective, the REXROTH R911338561 is valuable because compact servo drives are often installed in critical motion sections of production equipment. Even a small auxiliary axis can stop a complete machine if it controls feeding, positioning, labeling, clamping, or synchronization. Keeping the correct type code in inventory can shorten downtime, but only if the replacement unit matches the original hardware configuration, firmware requirement, parameter file, communication setup, and motor feedback system.
For sellers, the commercial condition should be stated separately from the technical product identity. If the unit is brand new, new surplus, used tested, or refurbished, that condition should be listed clearly in the quotation or product page. Warranty, lead time, test status, packaging method, and shipping terms should also be written separately. The condition should not modify the official order number or model code.
In summary, the REXROTH R911338561 HCS01.1E-W0003-A-02-B-ET-EC-PB-L3-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 platform and is suitable for cabinet-mounted use in packaging, feeding, handling, labeling, printing, inspection, assembly, and other automated machines. The estimated product net weight is approximately 1.3 kg, while the final gross weight should be verified after packing. For reliable sourcing, correct replacement, and effective Google search indexing, both the order number R911338561 and the full model code HCS01.1E-W0003-A-02-B-ET-EC-PB-L3-NN-FW should always be used together.
