Wonderful New Servo Drive Converter Rexroth R911339700 HCS01.1E-W0003-A-02-A-CC-EC-NN-NN-NN-FW Developed For Industrial Systems

The REXROTH R911339700 HCS01.1E-W0003-A-02-A-CC-EC-NN-NN-NN-FW is a compact single-axis servo drive converter developed for industrial motion-control systems that require stable power conversion, precise motor regulation, and efficient cabinet installation. This unit belongs to the Rexroth HCS01 compact converter range and is commonly used as part of an IndraDrive-based automation architecture. It is designed for low-power servo axes where accurate control, fast response, and dependable machine integration are more important than high output capacity.

The product is identified by the material number R911339700 and the full type code HCS01.1E-W0003-A-02-A-CC-EC-NN-NN-NN-FW. For industrial spare-parts supply, the complete type code should always be used together with the material number. The HCS01.1E-W0003 base section indicates a compact converter in the 3.3 A class, while the final configuration fields define the control, communication, encoder, safety, and firmware-related structure. This specific version uses the EC-NN-NN-NN-FW configuration, so it should not be confused with similar HCS01.1E-W0003 units that include ET, PB, S4, L3, L4, or other optional modules.

Product Overview

The main function of the R911339700 HCS01 compact converter is to supply and regulate power for a servo motor axis. In a machine-control system, the converter receives control commands from the automation controller and delivers a controlled output to the motor. This allows the motor to perform precise movement in speed, torque, or position-based applications. For small servo axes, this type of drive can help improve repeatability, reduce mechanical variation, and support consistent production quality.

This compact converter is especially useful in control cabinets where available space is limited. Machine builders often need to install multiple drives, power supplies, controllers, terminals, and safety components in one enclosure. A compact HCS01 unit helps reduce cabinet footprint while still providing a professional servo-drive solution for one axis. Its approximate 1.39 kg net weight also makes the unit easy to handle during installation, replacement, and export packing.

Key Technical Characteristics

The EC-NN-NN-NN-FW ending is important for replacement accuracy. Although many HCS01 compact converters appear similar from the front panel, their internal configuration can differ significantly. A converter with EC-NN-NN-NN-FW is not automatically interchangeable with a version using EC-ET-NN-NN-FW, EC-ET-L3-NN-FW, or EC-PB-L4-NN-FW. The communication interface, safety function, firmware condition, and machine parameter compatibility may be different. For this reason, buyers should confirm the full type code before ordering.

In practical applications, this drive converter can be used in equipment that requires controlled and repeatable low-power motion. It is suitable for indexing tables, small conveyor axes, feed mechanisms, test fixtures, assembly stations, packaging sub-axes, light-duty handling systems, and auxiliary positioning units. It is not intended to replace a high-power main spindle drive or a large motor inverter. Its strength is compact servo control for smaller machine axes.

Application Reference

For maintenance engineers, this product is often purchased as a spare or replacement part. Before replacing an existing unit, it is recommended to back up the original drive parameters, check the motor and encoder cables, inspect the power supply condition, and verify the machine safety circuit. A drive fault is not always caused by the converter itself. Problems may also come from damaged motor windings, shielding failure, incorrect grounding, unstable mains voltage, overheating, brake circuit issues, or communication faults.

Replacement and Procurement Checklist

The product should be installed only in a suitable industrial electrical cabinet. Correct grounding, proper cable routing, shield connection, ventilation clearance, and parameter configuration are essential for stable operation. Servo drives can be sensitive to electrical noise and wiring quality, especially in machines with multiple axes, relays, contactors, and switching power supplies. Good installation practice can reduce nuisance faults and improve long-term reliability.

For export documents and online product listings, this unit can be described as a compact servo drive converter for industrial automation equipment. The net weight may be listed as approximately 1.39 kg, while the gross weight should be calculated according to the actual carton, foam, anti-static bag, moisture protection, and outer packaging. For international shipping, it is better not to use the net weight as the final gross weight unless the packed product has been measured.

Suggested Listing Information

The REXROTH R911339700 HCS01.1E-W0003-A-02-A-CC-EC-NN-NN-NN-FW is a compact and configuration-specific servo drive converter for industrial motion-control applications. It is best suited for low-power servo axes that require precise control, stable integration, and efficient cabinet use. Its value comes from the combination of compact hardware, single-axis control capability, and accurate matching with the machine’s original Rexroth drive configuration.

For engineers and purchasing teams, the most important rule is to avoid partial-code matching. The base model HCS01.1E-W0003 only identifies the general converter class. The complete model HCS01.1E-W0003-A-02-A-CC-EC-NN-NN-NN-FW and the material number R911339700 should both be confirmed before procurement. When the full configuration, firmware requirement, and machine parameters are correctly matched, this compact converter can provide a reliable replacement solution for automated production equipment, compact servo systems, and industrial machinery requiring precise single-axis motion control.
