| Place of Origin | Germany |
| Brand Name | REXROTH |

REXROTH R911371817 HCS01.1E-W0005-A-03-E-S3-EC-EP-NN-NN-FW is a compact IndraDrive Cs servo drive controller / compact converter for precise single-axis motion control in industrial automation equipment. It belongs to the HCS01.1E-W0005 current class and is intended for machines that require reliable servo performance, compact cabinet installation, encoder-based control, and integration with modern drive communication architecture.
This model should be described as a compact servo drive controller, not as a general AC inverter. A standard inverter usually controls motor speed with limited feedback requirements, while the Rexroth HCS01 platform is designed for servo applications where position, velocity, torque, motor feedback, firmware, communication settings, and machine parameters must work together. Public Rexroth product information for the HCS01 IndraDrive Cs compact converter family describes these units as lower-power compact converters combining power and control units in one device, with Ethernet-based communication, multi-encoder interface capability, integrated safety technology, high overload capacity, and compact single-axis construction.

The E-S3-EC-EP portion is the main difference between this unit and other HCS01.1E-W0005 variants. It should not be ignored. In Rexroth drive systems, suffix variations can represent differences in communication interface, encoder interface, safety configuration, firmware package, or controller compatibility. Two drives may share the same W0005 current rating but still be incompatible if the communication and option structure are different. Therefore, this product should be ordered as R911371817 HCS01.1E-W0005-A-03-E-S3-EC-EP-NN-NN-FW, not only as “HCS01 5A drive.”
Product Description
The REXROTH R911371817 HCS01.1E-W0005-A-03-E-S3-EC-EP-NN-NN-FW is built for compact motion control tasks where accurate and repeatable axis behavior is required. It controls a compatible servo motor according to command data from the machine controller and feedback data from the motor or encoder system. In actual machine use, this allows controlled acceleration, stable speed regulation, accurate stopping, torque control, and repeatable positioning.
The HCS01 platform is especially valuable in automation equipment where space is limited. Instead of using a large multi-axis cabinet structure for a small axis, the machine builder can use a compact single-axis converter. This makes the drive suitable for modular machine designs, compact production cells, retrofits, auxiliary axes, laboratory automation, printing equipment, feeder systems, and smaller packaging machines.
The W0005 class is a lower-current compact class, so it is normally selected for small servo axes rather than large main spindle or heavy-duty power axes. Typical applications include material feed rollers, label positioning axes, small rotary tables, indexing mechanisms, lightweight linear actuators, measuring slides, small pressing stations, dispensing axes, and product transfer mechanisms. In these applications, the main requirement is not only motor rotation but controlled motion that can be repeated cycle after cycle.
Technical and Functional Features
| Feature | Value for the User |
|---|---|
| Compact Converter Design | Saves cabinet space and simplifies machine layout |
| Integrated Power and Control Unit | Reduces component count compared with separated systems |
| Single-Axis Operation | Suitable for one controlled servo axis |
| 5 A W0005 Current Class | Fits low-power precision motion applications |
| Encoder-Based Control | Supports accurate servo feedback operation |
| EP / S3 Configuration | Important for matching the original machine communication setup |
| Firmware-Dependent Operation | Allows application-specific drive functions and parameters |
| Industrial Cabinet Mounting | Suitable for protected electrical control panels |
| High Overload Capability Family | Supports dynamic servo movement within rated limits |
| Full Type Code Identification | Helps avoid incorrect replacement and purchasing errors |
Because the HCS01 series uses firmware and parameter-based commissioning, the drive’s physical hardware is only one part of the final working system. The firmware version, motor data, feedback settings, communication configuration, and application parameters must also be correct. This matters especially when a unit is replaced in an existing machine. A drive that looks similar may fail to start if the parameter set or firmware level does not match the original machine.
Application Areas
| Industry | Typical Use |
|---|---|
| Packaging Machinery | Film feed, label feed, sealing axis, cutting axis, indexing axis |
| Assembly Automation | Small press axis, feeder slide, rotary table, transfer mechanism |
| Printing and Converting | Registration adjustment, roller feed, web handling auxiliary axis |
| Handling Systems | Pick-and-place movement, light gantry axis, compact linear module |
| Inspection Equipment | Controlled positioning for camera, probe, or measuring fixture |
| Laboratory Automation | Small motion modules requiring repeatable positioning |
| Retrofit Projects | Replacement of existing Rexroth IndraDrive Cs compact converters |
In packaging machinery, this drive may be used to synchronize a feed movement with a sealing or cutting process. In assembly automation, it may position a workpiece carrier or move a tool to a defined point. In testing equipment, it may move a fixture repeatedly through a programmed path. These are typical servo-drive tasks where repeatability and communication with the controller are more important than simple constant-speed motor operation.

Replacement and Compatibility Guidance
When replacing this drive, the most important rule is to match the complete configuration. A replacement should be checked against the original unit label, controller project, motor feedback system, and parameter backup. The S3, EC, and EP segments should be verified carefully because they may affect communication, encoder compatibility, and controller integration. The FW segment also matters because firmware is not just a label; it can determine available functions, parameter structure, and machine behavior.
A correct replacement process should include the following checks:
| Check Item | Why It Matters |
|---|---|
| Material Number R911371817 | Confirms the exact Rexroth product identity |
| Full Type Code | Confirms configuration compatibility |
| Firmware Version | Prevents drive function mismatch |
| Parameter Backup | Restores machine-specific axis settings |
| Motor Type | Ensures correct motor data and control behavior |
| Encoder Feedback | Prevents feedback interface or scaling faults |
| Communication Setup | Ensures the drive can communicate with the PLC or motion controller |
| Safety / Enable Wiring | Prevents startup and safety circuit problems |
| Cabinet Cooling | Supports stable operation under load |
If the original machine uses a dedicated controller project, parameter files should be backed up before removing the old drive. A replacement drive may require firmware loading, parameter transfer, address setting, or commissioning by Rexroth engineering software. This is especially important in OEM equipment, where the same hardware may be configured differently for different machine models.
