REXROTH HMV01.1R-W0018-A-07-FNN1 – IndraDrive M Regenerative Supply Unit

Product Overview

The REXROTH HMV01.1R-W0018-A-07-FNN1 is a regenerative supply unit from the Bosch Rexroth IndraDrive M HMV01.1 series. It converts incoming AC power into the controlled DC bus used by compatible IndraDrive controllers and can return regenerative energy to the mains during deceleration. The unit has an 18 kW rated continuous DC-bus power and a regulated DC-bus voltage of 750 V, while its nominal DC-bus classification is commonly listed as 700 V. Internal forced-air cooling uses an integrated blower, and the enclosure is rated IP20. Bosch Rexroth documentation identifies this type code as an HMV supply unit with regenerative power-supply configuration. It is intended for multi-axis servo systems where several drive controllers share a common DC bus and controlled regeneration is required.

Technical Specifications — HMV01.1R-W0018-A-07-FNN1

The 18 kW continuous rating, 45 kW maximum DC-bus capability, 750 V regulated bus, and 0.70 mF internal capacitance are documented in Rexroth HMV technical data.

Key Features and Benefits — HMV01.1R-W0018-A-07-FNN1

• 18 kW continuous DC-bus power for multi-axis servo applications.
• Regenerative supply architecture returns suitable braking energy to the mains.
• 750 V regulated DC bus supports compatible IndraDrive power sections.
• Integrated blower provides forced-air cooling for cabinet operation.
• Common DC-bus design allows multiple drive axes to share a centralized power supply.
• IP20 construction is intended for installation inside a protected electrical cabinet.
• 45 kW maximum DC-bus power provides additional capacity during short-duration regenerative conditions.

Personally, I would verify the mains-side configuration and connected DC-bus load before selecting a replacement. The 18 kW continuous rating and 45 kW maximum bus-power figure serve different purposes, so sizing the unit from the peak value alone can give a misleading result.

Installation and Maintenance — HMV01.1R-W0018-A-07-FNN1

Before installation, verify the incoming mains configuration, DC-bus voltage, connected drive controllers, regenerative load profile, braking requirements, and cabinet ventilation. Because the DC bus operates at hazardous voltage levels, isolation and discharge procedures must be completed before maintenance.

Keep the air inlet and blower path clear. During preventive maintenance, inspect power terminals, DC-bus connections, cooling fan operation, grounding connections, and visible signs of thermal stress. After replacement, verify the DC-bus voltage, supply diagnostics, connected drive communication, and regeneration behavior before releasing the machine for production.

Product Warranty — HMV01.1R-W0018-A-07-FNN1

Warranty coverage depends on supplier condition and sales terms. Confirm whether the unit is new, refurbished, repaired, or surplus, and request the exact type code, order number, inspection records, functional test results, and warranty period.

The REXROTH HMV01.1R-W0018-A-07-FNN1 is a configuration-specific IndraDrive M supply unit, so exact type-code matching should be used when replacing a legacy common-DC-bus installation.
