Product Description:

The HMV01.1R-W0018-A-07-NNNN-AA is a regenerative power supply module produced by Bosch Rexroth Indramat in the HMV IndraDrive Supply Units series. It connects the three-phase mains to a shared DC bus for multiple IndraDrive inverters. This arrangement allows several axes to draw energy from one source while keeping the bus stable during changing load conditions. Because the DC bus is shared, simultaneous axis motion can be supplied without adding a separate mains section for each inverter. In machine-tool, packaging, and material-handling systems, the module can return braking energy to the grid instead of dissipating it inside the cabinet.

The unit regulates its DC link at DC 700 V. It can deliver up to 18 kW of continuous power, which supports moderate multi-axis loads from a single supply source. The power stage is regenerative, so energy from decelerating axes can flow back to the mains rather than into a brake resistor. Returned energy is handled by the supply module, which helps reduce waste heat during frequent deceleration cycles. Thermal management uses internal air cooling with an integrated blower, which requires clear airflow space inside the switchgear cabinet. The housing has an IP20 rating, providing finger-safe protection for installation in an enclosed electrical cabinet.

The unit is Design Version 1 and Series Version 01. It is classified as an HMV supply unit, so it is placed ahead of converter modules on the common DC bus. That layout lets one supply section serve several inverters in a coordinated drive system. It also supports applications where energy released by one axis can be made available to other axes before excess power is returned to the line. This centralized arrangement simplifies the power path inside cabinets that group several servo drives on a common bus structure.
