Rexroth R911339368 HCS01.1E-W0003-A-02-B-ET-EC-CN-L3-NN-FW Compact Servo Drive Converter 3.3A 1.39kg

The REXROTH R911339368 HCS01.1E-W0003-A-02-B-ET-EC-CN-L3-NN-FW is a compact IndraDrive servo converter developed for precise single-axis motion control in industrial automation systems. It is part of the Rexroth HCS01 compact converter platform, a drive family designed for machines that require efficient cabinet installation, stable servo motor control, and configuration-specific integration with industrial controllers. This model is suitable for low-power servo axes where compact design, correct communication matching, safety configuration, and reliable motion performance are essential.

This product is identified by the material number R911339368 and the full type code HCS01.1E-W0003-A-02-B-ET-EC-CN-L3-NN-FW. For procurement and replacement, both references should be used together. The material number confirms the commercial part identity, while the full type code defines the hardware and option structure. The base section HCS01.1E-W0003 places the unit in the small HCS01 converter class, commonly associated with a 3.3 A class compact single-axis converter. The option sequence B-ET-EC-CN-L3-NN-FW is important because it distinguishes this unit from similar HCS01.1E-W0003 variants with A control sections, PB fieldbus options, NN-only option endings, or different safety configurations.

Product Identification Table

The main function of the R911339368 compact servo converter is to regulate the electrical output supplied to a connected servo motor. In a complete machine system, the converter receives control commands from the controller, processes feedback from the motor or encoder system, and delivers controlled motor output for accurate movement. This enables the servo axis to perform positioning, speed control, torque-related movement, and repeatable machine sequences.

Compared with large drive systems used for high-power motors, this HCS01 unit is designed for compact automation tasks. It is not intended to act as a heavy spindle drive or a high-output inverter. Its practical value is in small servo axes where fast response, cabinet space saving, and configuration accuracy matter more than high power. Typical examples include feed mechanisms, indexing stations, label control axes, compact handling modules, inspection stages, actuator adjustments, and light-duty positioning systems.

Configuration and Functional Meaning

The CN-L3 part of the model code is especially important for replacement work. HCS01 compact converters can look almost identical from the outside, but option differences can affect commissioning, safety behavior, communication with the controller, and compatibility with the existing machine program. A unit marked B-ET-EC-CN-L3-NN-FW should not be treated as automatically interchangeable with versions such as A-CC-EC-NN-NN-NN-FW, A-CC-EC-PB-NN-NN-FW, or B-ET-EC-NN-L4-NN-FW. Even when the base power section is still HCS01.1E-W0003, the configuration fields can change the practical replacement result.

Key Product Features

The approximate 1.39 kg net weight is suitable for product listing, spare-parts cataloging, and preliminary logistics planning. For export packing, this value should be treated as the unpacked product weight. The actual gross weight may be higher after adding carton packaging, foam, anti-static protection, moisture protection, labels, and outer packing materials. For commercial invoices, it is better to list the product as a compact servo drive converter for industrial automation equipment and separate net weight from gross weight where possible.

Typical Application Areas

For maintenance teams, this product is often needed when an installed Rexroth IndraDrive system reports a drive fault or when a spare unit is required for production continuity. Before replacing the original converter, the technician should confirm the full nameplate code, save the existing parameter set if possible, and check whether the fault may be caused by external components. Motor cable insulation problems, encoder cable damage, poor grounding, unstable input power, overheating, contaminated cabinet air, brake circuit faults, or communication interruptions may all create symptoms that appear similar to drive failure.

Replacement Checklist

Correct commissioning is as important as selecting the correct part number. A replacement unit may require firmware installation, parameter loading, address setting, fieldbus configuration, and safety validation before the machine can run normally. If the original drive contains a programming module or stored parameters, those settings should be handled carefully. In some machines, the drive will not operate correctly if the firmware version or parameter structure does not match the controller project.

Recommended SEO Product Listing Information

The REXROTH R911339368 HCS01.1E-W0003-A-02-B-ET-EC-CN-L3-NN-FW is a configuration-specific compact servo converter for low-power industrial motion-control applications. Its main advantage is not only its small physical size, but also its ability to integrate into Rexroth-based automation systems with the correct communication, feedback, safety, and firmware configuration. For buyers and engineers, the most important rule is to avoid selecting a replacement only by the first part of the type code. The complete model code and the material number must match the machine requirement.

When correctly selected, parameterized, and installed, this compact IndraDrive converter can support stable servo-axis operation in packaging machines, assembly systems, material handling equipment, inspection devices, and other automated production machinery. Its compact construction, approximate 1.39 kg net weight, and clearly defined B-ET-EC-CN-L3-NN-FW configuration make it a practical spare part for users maintaining Rexroth HCS01-based motion-control systems.
