The REXROTH R911381753 HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW is an IndraDrive Cs compact servo drive controller developed for precise single-axis motion control in industrial automation systems. It is part of the HCS01 compact converter platform, a drive family designed to combine power electronics and control electronics in one cabinet-mounted unit. The HCS01 series is positioned for compact machine axes where space saving, flexible communication, encoder feedback, and reliable servo performance are required. Official product-family information describes IndraDrive Cs as a compact servo drive system with multiprotocol capability, continuous power coverage up to 14 kW, integrated safety technology, and use in machine tools, assembly, handling, packaging, processing, printing, and converting applications.

For this specific item, the order number is R911381753 and the complete type code is HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW. The full model string should be kept unchanged in procurement documents, replacement orders, warehouse labels, and technical quotations. HCS01 models can look very similar externally, but a small change in the suffix may indicate a different communication interface, encoder interface, safety option, firmware arrangement, or control section. For that reason, matching only “HCS01.1E-W0006” is not sufficient when replacing a drive in an existing machine.

The W0006 section identifies the 6 A current class. Rexroth HCS01 project planning data lists the HCS01.1E-W0006-A-02 group with 2.4 A continuous current and 6.0 A maximum current. This makes the unit suitable for smaller servo axes where controlled acceleration, accurate positioning, and repeatable speed regulation are more important than high continuous power output. Typical axes include indexing tables, feeder drives, small rotary axes, light-duty linear slides, printing auxiliaries, labeling units, electronic assembly stations, and compact handling modules.

The A-02 voltage and design section places this model in the lower-voltage HCS01 group. Project planning documentation lists HCS01.1E-W0006-A-02 together with the HCS01.1E-W0003-A-02, W0009-A-02, W0013-A-02, and W0018-A-02 variants in the mains supply tables for the 110–230 V class. In practical terms, this model should be treated as a low-voltage cabinet drive and must be checked against the actual machine supply, grounding system, line protection, and motor data before commissioning.

The product weight should be stated conservatively. For the HCS01.1E-W0006-A-02 class, third-party industrial listings commonly state an approximate controller weight of 1.30 kg for similar W0006-A-02 HCS01 configurations, while shipping weight may be higher because of carton, foam, control panel, documentation, and accessory packaging. For export packing, spare-parts quotation, and logistics preparation, it is safer to write approx. 1.30 kg net weight and verify the actual packed weight from the physical unit before booking freight.

A key feature of the REXROTH R911381753 HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW is its communication-oriented configuration. The CC section is commonly associated with SERCOS-based control architecture, which is useful in synchronized motion systems that require deterministic communication between controller and drive. In a machine using several coordinated axes, deterministic drive communication helps the controller maintain timing accuracy, reduce synchronization errors, and improve repeatability during cyclic motion. This matters in equipment such as rotary indexing systems, synchronized feeding mechanisms, compact packaging machines, printing modules, and high-speed assembly cells.

The EC part indicates a multi-encoder interface configuration. This is important because servo performance depends heavily on feedback quality. The drive must read position, velocity, and motor feedback correctly before it can regulate torque, speed, and position. A multi-encoder interface gives the drive flexibility when working with compatible Rexroth servo motors and suitable feedback systems. When replacing the unit, technicians should check motor type, encoder cable, feedback protocol, and parameter backup. A physically compatible drive may still fail commissioning if encoder configuration or firmware setup does not match the original machine data.

The REXROTH R911381753 HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW is not a general-purpose variable frequency drive for simple asynchronous motor control. It is a servo drive controller intended for controlled motion applications where the machine requires accurate dynamic response. In service, it receives commands from the automation controller, processes feedback from the encoder system, regulates the motor current loop, and executes configured drive functions according to firmware and parameter settings. The result is controlled axis behavior, including acceleration, deceleration, holding torque, speed control, and positioning performance.

Because the device is an IP20 cabinet-mounted unit, installation conditions matter. It should be mounted inside a suitable electrical enclosure with correct protective grounding, adequate ventilation, controlled cabinet temperature, and protection against conductive dust, oil mist, moisture, and accidental contact. The wiring layout should separate power cables from signal cables where possible. Motor cables, encoder cables, grounding conductors, shield connections, line protection, and braking circuits should be checked carefully. Poor grounding or incorrect shielding can cause communication faults, encoder errors, unstable motion, or electromagnetic interference.

For replacement work, the safest procedure is to record the old drive type code, order number, firmware information, motor type, axis name, and parameter set before removing the original drive. If the old drive is still readable, the parameter backup should be saved before replacement. After installation, the new or refurbished unit should be checked for the correct firmware level, communication address, safety setting, motor data, encoder configuration, and application parameters. Power should not be applied casually without confirming wiring and machine safety status.

From a procurement perspective, R911381753 should be treated as the primary order number, while HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW should be treated as the full technical configuration. Both should appear in the product title, quotation line, packing list, and internal inventory record. If the item is offered as refurbished or used, the quotation should also state the condition, testing scope, warranty period, firmware availability, and whether a control panel is included.

In summary, the REXROTH R911381753 HCS01.1E-W0006-A-02-A-CC-EC-CN-NN-NN-FW is a compact IndraDrive Cs HCS01 servo drive controller for low-power industrial motion axes. It provides a 6 A maximum current class, a compact cabinet-mounted design, encoder feedback support, communication-oriented drive integration, and a practical weight reference of approximately 1.30 kg net weight. It is best suited for compact automation equipment where accurate servo control, synchronized machine operation, and correct replacement matching are essential. For reliable use, the full type code, firmware, motor compatibility, encoder configuration, and machine parameters must be verified before installation.
