Recision Original New Power Supply Module Rexroth R911297460 HMV01.1R-W0018-A-07-NNNN for Industrial Application
The REXROTH R911297460 HMV01.1R-W0018-A-07-NNNN is an industrial IndraDrive M regenerative power supply unit used in modular servo drive systems. It is designed to provide a stable DC bus supply for connected Rexroth drive controllers in multi-axis automation equipment. This model is identified by public product listings as a power supply unit with the full type code HMV01.1R-W0018-A-07-NNNN and material number R911297460. It belongs to the HMV01.1R regenerative supply family and is commonly used in machine tools, printing machines, packaging equipment, robotic systems, and other industrial motion control applications where stable DC link power and regenerative energy handling are required.
Unlike a standard feeding supply unit, the HMV01.1R-W0018-A-07-NNNN is built for regenerative operation. During machine deceleration, lowering movement, or braking cycles, servo motors may return energy into the drive system. A regenerative supply unit helps process this returned energy and supports efficient DC bus management. In practical industrial equipment, this can reduce heat load compared with purely resistive braking solutions and improve the energy behavior of machines with frequent start-stop operation.

The 18 kW power class makes this unit suitable for medium-power modular drive systems. It is not simply a passive power converter; it is a key part of the drive power architecture. In an IndraDrive M system, the HMV supply unit feeds the common DC bus, while connected drive controllers use this DC bus to control servo motors, spindle motors, or other motion axes. Wake Industrial identifies this model as a regenerative HMV supply unit with 18 kW rated output power, internal air cooling, and IP20 protection.

Public product data lists approximate dimensions for this model as 32.0 cm height, 48.0 cm length, and 18.0 cm width. These dimensions are useful for warehouse handling, replacement planning, and cabinet space checking, but installation should still be verified against the original Rexroth manual and the actual machine layout.
Functional Role in a Drive System
| Function | Explanation |
|---|---|
| DC Bus Supply | Provides the DC link power for compatible downstream drive modules |
| Regenerative Operation | Handles energy returned from braking or decelerating motors |
| System Power Stabilization | Helps maintain suitable DC bus behavior in multi-axis operation |
| Cabinet Integration | Designed for installation inside industrial electrical cabinets |
| Thermal Control | Uses internal air cooling to manage heat during operation |
| Service Replacement | Can be used as a spare part when the original HMV01.1R unit fails |
The HMV01.1R unit is normally used in systems where multiple axes are supplied from one common power stage. This architecture is common in automated production machinery because it improves cabinet organization and allows several drive controllers to share one DC bus. For machines with frequent acceleration and braking, regenerative supply capability is especially important because the electrical energy returned by motors must be handled safely and efficiently.
Application Areas
| Application Field | Typical Use of R911297460 HMV01.1R-W0018-A-07-NNNN |
|---|---|
| CNC Machine Tools | Supplies feed axes, auxiliary axes, or modular drive groups |
| Printing Machinery | Supports synchronized rollers, tension axes, and high-speed motion |
| Packaging Equipment | Provides power for sealing, cutting, indexing, and conveyor axes |
| Robotics | Supports coordinated multi-axis servo drive systems |
| Material Handling | Helps operate lifting, transfer, positioning, and conveying equipment |
| Textile Machinery | Used in machines requiring stable, repeatable drive control |
| Automated Assembly Lines | Provides centralized power for modular drive stations |
This product is often selected as a replacement component for existing Rexroth IndraDrive M systems. When replacing an HMV unit, the full type code must be checked carefully. A similar HMV01 housing does not guarantee full compatibility. Differences in power rating, regenerative function, DC bus configuration, cooling design, or option code can affect system operation.
Installation and Replacement Considerations
| Checkpoint | Practical Recommendation |
|---|---|
| Type Code Verification | Confirm HMV01.1R-W0018-A-07-NNNN exactly |
| Material Number Verification | Match R911297460 where possible |
| Power Rating | Confirm that the original system requires 18 kW |
| DC Bus Compatibility | Check compatibility with connected HMS or HMD drive modules |
| Cooling Clearance | Keep the air path unobstructed inside the cabinet |
| Electrical Safety | Disconnect and discharge the system before service |
| Grounding | Follow protective earth and EMC grounding rules |
| Condition Check | Inspect terminals, labels, fan area, and housing before installation |
Because this product works with high DC bus voltage, it should only be installed by qualified electrical or automation personnel. Even after the mains supply is switched off, drive systems can retain hazardous voltage in the DC link. Proper lockout, waiting time, measurement, and discharge procedures must be followed according to the applicable Rexroth documentation and local electrical regulations.
