Original Brand New Servo Drive Converter Rexroth R911339699 HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW

The REXROTH R911339699 HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW is a compact single-axis servo drive converter designed for precise motion control in industrial automation systems. As part of the HCS01 compact converter family, this unit is commonly used in applications where a small installation footprint, stable servo performance, and flexible communication capability are required. It is suitable for machine builders, maintenance teams, system integrators, and automation equipment suppliers who need a reliable drive solution for low-power servo axes.

This model is built around the HCS01.1E-W0003 power class, which is associated with a 3.3 A maximum current rating and compact cabinet installation requirements. The product is designed to convert incoming supply power into a controlled output for servo motor operation, helping the connected motor achieve accurate speed, torque, and position control. In practical automation projects, this type of drive is often used in packaging machinery, small handling units, positioning tables, light-duty assembly systems, indexing mechanisms, feeder axes, laboratory automation equipment, and compact production machines.

Basic Product Information

The most important value of the REXROTH R911339699 HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW is its ability to combine compact drive hardware with motion-control functions in a small cabinet space. In many industrial machines, control cabinet space is limited. A compact converter like this helps reduce cabinet layout pressure while still providing the electrical and control functions required for a servo axis. For equipment manufacturers, this can simplify system design. For spare-part buyers, it also provides a direct replacement reference when the full order number and type code are confirmed.

The HCS01.1E-W0003 platform is positioned for smaller servo power requirements. It is not intended for heavy spindle control or high-power main drive tasks. Instead, it is better matched with compact servo motors and low-to-medium mechanical loads where controlled movement is more important than high output power. Typical examples include pick-and-place axes, label positioning systems, small conveyors, cam-driven auxiliary axes, inspection stations, dosing equipment, and automated adjustment mechanisms.

Technical Features

For maintenance departments, the full model code is especially important. Rexroth drive type codes are configuration-specific. A small difference in one option field may change the communication interface, encoder compatibility, safety function, firmware behavior, or control-section characteristics. Therefore, when replacing an existing drive, the safest method is to compare both the order number R911339699 and the full type code HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW with the installed unit. Matching only the first part of the model code is not enough for a risk-free replacement.

In production environments, this compact drive can help improve machine repeatability and motion stability. Servo systems require accurate feedback, predictable response, and fast control behavior. The HCS01 compact converter design supports these requirements by providing controlled electrical output to the connected servo motor. When properly parameterized, it can help the machine maintain consistent positioning accuracy, smooth acceleration, stable deceleration, and reliable stop behavior.

Application Fields

The compact size and moderate weight of approximately 1.39 kg unpacked also make the unit practical for international spare-parts logistics. For export documentation, it can be described as a compact servo drive converter for industrial automation equipment. If packaging is included, the shipping weight should not be written as the same as the bare product weight. A safe logistics estimate may need to account for carton, anti-static protection, foam, moisture protection, and outer packaging. For commercial invoices or export packing lists, it is better to separate net weight and gross weight where possible.

From an installation perspective, the unit should be mounted inside a suitable electrical cabinet with proper ventilation, grounding, and wiring practices. Servo drives generate heat during operation, even in low-power applications. Incorrect cabinet spacing, blocked air paths, poor grounding, unstable supply voltage, or incorrect motor cable shielding can cause commissioning problems or long-term reliability issues. The drive should be installed by qualified automation or electrical personnel according to the machine design and applicable safety requirements.

Procurement and Replacement Notes

This product is especially relevant for users maintaining older Rexroth IndraDrive-based machines. In many factories, compact drive converters remain in service for years, and failures often occur because of power supply stress, environmental heat, aging components, poor cabinet ventilation, or external motor/cable problems. Before replacing the drive, it is useful to check whether the original fault is caused by the drive itself or by the connected motor, encoder cable, motor power cable, brake circuit, DC bus condition, or control communication issue. Replacing the drive without checking the surrounding system may lead to repeated faults.

The REXROTH R911339699 HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW is a practical compact servo drive for low-power motion axes where accurate control, small cabinet footprint, and configuration-specific replacement are important. Its value is not only in the hardware itself, but also in the correct match between order number, firmware, encoder interface, communication option, safety configuration, and the machine program. For buyers, the best procurement practice is to provide a clear photo of the nameplate, confirm the full type code, confirm whether firmware is included, and check whether the unit is new, used, tested, or refurbished.

Standard English Description for Export or Product Listing

Overall, the REXROTH R911339699 HCS01.1E-W0003-A-02-A-CC-EC-ET-L3-NN-FW is a compact and application-focused servo drive converter for industrial automation systems. It is most suitable for users who need a space-saving single-axis drive solution with precise motor control capability. For Google-indexed product pages, the full order number, full model code, product type, approximate weight, application fields, and replacement notes should all be included clearly, because these are the search terms most likely to be used by engineers, buyers, and maintenance personnel looking for the exact spare part.
