New Original Power Supply Module Rexroth R911296878 HMV01.1E-W0030-A-07-NNNN Used In Professional Servo Drive Systems

The REXROTH R911296878 HMV01.1E-W0030-A-07-NNNN is an industrial power supply module from the Rexroth IndraDrive HMV series, designed for demanding servo drive and automation systems that require a stable DC bus supply, reliable power conversion, and robust mechanical construction. This unit is commonly used in machine tools, packaging machinery, printing equipment, material handling systems, production lines, and other industrial automation environments where multiple servo axes must be supplied from a centralized power source.

The type code HMV01.1E-W0030-A-07-NNNN identifies this product as an HMV01 supply unit with a rated power class of approximately 30 kW. Public industrial automation references list the unit as a Rexroth IndraDrive power supply module with 30 kW output class, DC bus voltage around 700 V, and internal air cooling by integrated blower. The order number R911296878 is an important purchasing and identification reference, especially when checking compatibility, replacement requirements, or spare part availability. A distributor listing confirms the association between R911296878 and HMV01.1E-W0030-A-07-NNNN as a Rexroth power supply unit.

Main Product Information

The physical weight of the HMV01.1E-W0030-A-07-NNNN is commonly listed as 13.5 kg, with one automation supplier also listing approximate dimensions of 48 cm length, 31 cm height, and 15 cm width. For international shipping, the packed shipping weight may be higher; one marketplace listing gives a shipping weight of 35 lbs and shipping dimensions of 27 × 17 × 13 inches. For export, quotation, or freight calculation, the packed size should be confirmed before shipment because carton, foam, pallet, and protection materials can change the final chargeable weight.

Functional Overview

The Rexroth HMV01.1E-W0030-A-07-NNNN is used to supply energy to IndraDrive drive systems through a DC bus. In a typical servo drive cabinet, the supply module receives three-phase mains input and converts it into a stable DC link that can feed connected drive controllers or inverter modules. This architecture is widely used in multi-axis industrial equipment because it allows several servo axes to share one common supply source.

The 30 kW rating makes this unit suitable for medium-power automation systems where multiple motors may operate together under coordinated motion control. Applications may include CNC machine axes, rotary tables, automated loading systems, robotic handling units, cutting machines, test benches, and high-speed manufacturing equipment. In these systems, the power supply must maintain stable performance under load changes, acceleration, deceleration, and continuous production cycles.

The integrated cooling structure is another important feature. Because industrial power supply modules generate heat during operation, internal air cooling helps maintain operating stability and prevents excessive temperature buildup inside the drive cabinet. Good cabinet ventilation, correct mounting clearance, and clean airflow paths are still necessary. Dust, blocked filters, insufficient cabinet space, or high ambient temperature can shorten the service life of the supply unit and connected drive components.

Design and Construction

The HMV01.1E-W0030-A-07-NNNN uses a metal industrial housing designed for control cabinet installation. The enclosure is built for mechanical stability, heat dissipation, and long service life in industrial environments. The module typically includes connection terminals, DC bus interfaces, control connections, warning labels, and installation points required for integration into Rexroth IndraDrive systems.

The weight of approximately 13.5 kg indicates that the module is not a small control accessory but a substantial power conversion device. During installation or replacement, proper handling is necessary. The unit should be mounted securely in accordance with the original cabinet layout and grounding requirements. Incorrect installation, poor contact at power terminals, or unsuitable replacement selection can cause system faults, drive alarms, overheating, or damage to connected drive modules.

Compatibility Considerations

When replacing an existing power supply module, the complete type code must be checked carefully. For this product, both identifiers should be kept together:

The order number is useful for procurement and inventory matching, while the type code describes the technical configuration. In industrial maintenance, relying only on a partial model such as “HMV01.1E-W0030” may create risk because suffix characters can define important configuration differences. The safest replacement method is to match the full type code from the nameplate and confirm the connected drive system, mains voltage, DC bus structure, firmware environment, and cabinet wiring.

The HMV series is normally associated with Rexroth IndraDrive systems. It should not be treated as a universal power supply for unrelated servo systems unless an engineering review confirms electrical and functional compatibility. The unit should be installed by qualified technicians familiar with high-voltage drive equipment.

Typical Application Areas

In these industries, machine downtime can be expensive. A failed supply module may stop several drive axes at once, so keeping a compatible spare unit can reduce production risk. For factories using older IndraDrive systems, the HMV01.1E-W0030-A-07-NNNN is often searched as a replacement, repair, or refurbished automation spare part.

Advantages for Industrial Users

The main advantage of the Rexroth R911296878 HMV01.1E-W0030-A-07-NNNN is its role as a dedicated supply module for professional servo drive systems. It is designed for continuous industrial operation rather than light-duty electrical use. Its 30 kW power class supports demanding machinery, while the DC bus architecture allows stable power distribution to connected drive components.

Another practical advantage is serviceability. Since the product is identified by both order number and type code, maintenance teams can search inventory, compare replacement units, and request quotations more accurately. This reduces the chance of receiving an incompatible unit. For buyers, the correct full designation should always be written as REXROTH R911296878 HMV01.1E-W0030-A-07-NNNN.

Buying and Inspection Notes

Before purchasing this model, users should check the product condition carefully. New, used, refurbished, and repaired units may all be available in the industrial automation spare parts market. Important inspection points include the nameplate, terminals, DC bus connectors, fan condition, housing damage, internal contamination, and previous repair history. For used or refurbished units, functional testing under suitable conditions is recommended before installation into production equipment.

For export or shipping, the approximate product weight is 13.5 kg, but the packed weight may be closer to 35 lbs depending on packaging method. If the unit is shipped internationally, protective packaging is important because the module contains power electronics, terminals, and mechanical structures that may be damaged by shock or vibration during transportation.

Conclusion

The REXROTH R911296878 HMV01.1E-W0030-A-07-NNNN is a 30 kW-class IndraDrive HMV01 power supply module used in professional servo drive systems and industrial automation machinery. With a listed product weight of approximately 13.5 kg, internal air cooling, and a DC bus supply function, it is suitable for medium-power multi-axis drive applications. For replacement or procurement, users should always verify the full order number and type code to avoid compatibility errors. This product is best suited for maintenance teams, machine builders, and automation service providers who need a reliable Rexroth IndraDrive power supply solution for industrial equipment.
