Brand New Power Supply Module Rexroth R922002789 HMV01.1E-W0075-A-07-FCN1 for Industrial Equipment

The REXROTH R922002789 HMV01.1E-W0075-A-07-FCN1 is an industrial power supply unit designed for use within Rexroth IndraDrive multi-axis drive systems. This unit belongs to the HMV01 supply module family, which is used to generate and stabilize the DC bus voltage required by connected inverter modules and servo drive axes. In a modern automation system, the power supply module is not just an auxiliary component. It is the central energy interface between the three-phase mains supply and the complete servo drive architecture.

The model HMV01.1E-W0075-A-07-FCN1 is generally associated with a 75 kW power class, making it suitable for medium to high power industrial motion applications. It is commonly used in machine tools, printing machinery, packaging lines, metal processing equipment, material handling systems, and other automated production machines where reliable DC bus supply is required for several coordinated servo axes.

This product is suitable for users who need a robust Rexroth IndraDrive supply unit for replacement, repair, retrofit, or spare parts inventory. Because HMV01 supply modules are often used in integrated automation cabinets, correct model identification is essential. The complete type code HMV01.1E-W0075-A-07-FCN1 should always be checked carefully against the original machine nameplate, drive cabinet documentation, and connected drive modules before replacement.

Basic Product Information

Technical Description

The REXROTH HMV01.1E-W0075-A-07-FCN1 is designed to supply DC bus power to Rexroth IndraDrive inverter modules. In a multi-axis servo drive system, the power supply unit converts the incoming three-phase AC supply into a controlled DC bus. The connected drive modules then use this DC bus to power servo motors, spindle motors, or other controlled motion axes.

The W0075 section of the model code indicates the 75 kW power class. This makes the unit appropriate for machines with demanding dynamic loads, multiple axes, or high continuous power requirements. Compared with smaller supply modules, a 75 kW supply unit provides a stronger energy base for applications where several servo axes accelerate and decelerate repeatedly during the production cycle.

The A-07 section is associated with the DC bus voltage class, commonly around the 700 V DC level used in Rexroth IndraDrive systems. The FCN1 suffix should be treated as part of the complete configuration code. When replacing this unit, the suffix is important because different suffixes can indicate different interface, control, or configuration details. A visually similar HMV01.1E-W0075 unit may not always be a direct replacement if the full type code is different.

Weight and Mechanical Data

The approximate product weight of the HMV01.1E-W0075-A-07-FCN1 is 22 kg. This weight is important for logistics, cabinet servicing, installation planning, and export packing. For shipping calculation, the gross packed weight may be higher than the net product weight because of carton, foam, wooden case, moisture protection, and outer packaging materials.

For international trade, it is not recommended to calculate freight only from the net weight. A 22 kg drive supply module normally requires protective industrial packaging. If the item is exported by air freight, courier, or sea freight, the final chargeable weight may depend on both actual weight and volumetric weight.

Functional Role in an IndraDrive System

The main role of the REXROTH R922002789 HMV01.1E-W0075-A-07-FCN1 is to act as the power feeding unit for the drive system. It receives power from the three-phase mains supply and provides the DC link required by downstream drive components. In a complete Rexroth drive cabinet, the HMV01 unit is normally installed together with inverter modules, control sections, line filters, mains chokes, braking resistors, safety circuits, and servo motor cables.

A stable DC bus is essential for motion accuracy. If the supply unit is unstable, undersized, damaged, or incorrectly configured, the connected servo axes may show alarms, undervoltage faults, braking faults, power loss, or unexpected shutdowns. For this reason, replacing the supply unit with the correct model is more reliable than using a partially matched alternative.

The 75 kW rating gives this model enough capacity for demanding automation environments. It can be used where machine operation requires frequent acceleration, controlled deceleration, high spindle load, or synchronized motion between several axes.

Typical Applications

The unit is especially relevant for maintenance teams and automation service companies working with Rexroth IndraDrive M systems. In many factories, downtime caused by a failed supply module can stop the whole machine, because several drive axes may depend on the same DC bus. Keeping a compatible HMV01 supply unit in stock can reduce recovery time.

Key Features

Replacement and Compatibility Notes

Before using REXROTH R922002789 HMV01.1E-W0075-A-07-FCN1 as a replacement unit, users should compare the full model code with the original installed device. The most important matching points include:

The model should not be selected only by appearance. Rexroth HMV01 units can look similar from the outside, but the internal rating and configuration may differ. For critical equipment, the safest method is to verify the original part number, complete type code, hardware index, electrical cabinet drawing, and drive system documentation.

Installation Considerations

The HMV01.1E-W0075-A-07-FCN1 should be installed by qualified electrical or automation personnel. Because the unit works with high voltage DC bus circuits, proper safety procedures are required before removal, installation, or inspection. The DC bus can retain dangerous voltage after power-off, so discharge time and safety measurement should be respected.

Adequate cabinet ventilation is also important. Internal air cooling depends on proper airflow. If the cabinet temperature is too high, the fan path is blocked, or the unit is installed too close to other heat-generating components, the service life of the power electronics may be reduced. For machines operating in dusty, oily, or high-temperature environments, periodic cabinet inspection is recommended.

SEO-Oriented Product Summary

The REXROTH R922002789 HMV01.1E-W0075-A-07-FCN1 is a 75 kW IndraDrive HMV01 power supply unit for industrial servo drive systems. It is used to generate the DC bus voltage required by Rexroth multi-axis drive modules. With an approximate weight of 22 kg and compact cabinet-mounted dimensions of about 440 × 250 × 262 mm, this supply module is suitable for machine tools, packaging machines, printing equipment, automated production lines, and retrofit maintenance projects.

For buyers searching for REXROTH HMV01.1E-W0075-A-07-FCN1, R922002789 power supply unit, IndraDrive HMV01 75 kW supply module, or Rexroth servo drive power supply replacement, this product is a practical choice when the complete machine configuration matches the original installed unit. The full type code should always be confirmed before purchase to avoid compatibility issues with similar HMV01 variants.

Final Note

The REXROTH R922002789 HMV01.1E-W0075-A-07-FCN1 is best positioned as a high-value industrial automation spare part rather than a general electrical component. Its value comes from correct compatibility with Rexroth IndraDrive systems, stable DC bus power supply, and suitability for demanding multi-axis motion applications. For procurement, the recommended confirmation points are the full model code, part number, net weight, physical dimensions, operating condition, and warranty terms.
