Product Description:

The HMV01.1R-W0075-A-07-FNN3 is a power conversion module assigned to the HMV IndraDrive Supply Units series. Acting as a common DC bus supply, it provides the regulated intermediate circuit energy that connected inverter axes draw for motoring and return during braking. In multi-axis machining centers, material-handling gantries, and printing lines, the unit stabilizes the DC link, absorbs regenerated energy, and feeds excess power back to the mains to improve overall energy balance. This arrangement lets several coordinated drives share one stabilized energy source instead of relying on a separate front-end unit for each axis.

The module delivers a rated output of 75 kW, indicating the continuous active power it can furnish to the shared bus without derating. Its internal circuitry is referenced to a nominal bus voltage of DC 700 V, so connected inverters must be sized for that potential. Cooling is handled by internal air cooling with an integrated blower; the embedded fan pulls cabinet air through the heat sink to maintain semiconductor temperatures within their operating range. During deceleration or overhauling load events, the supply operates in regenerative mode, channeling surplus DC energy back into the facility's three-phase utility rather than converting it to heat. An enclosure classification of IP20 protects against finger contact with live parts, while the open vents required for airflow mean it is not intended for exposure to liquids or conductive dust.

The unit is produced by Bosch Rexroth Indramat in version 1 and belongs to series 01. As a supply unit, it forms the front end of an IndraDrive DC bus segment so drive amplifiers can focus on motor control tasks. Because braking energy is returned through the supply section, the cabinet does not need to dissipate routine regenerative energy solely as heat. Its mechanical form factor, electrical terminations, and thermal path follow the conventions used across the line, which supports orderly placement with related modules in multi-axis cabinets.
