Product Description:

The HMV02.1R-W0015-A-07-NNNN-AA belongs to the HMV IndraDrive Supply Units series produced by Bosch Rexroth Indramat. It is intended to feed and stabilize the DC bus in multi-axis drive arrangements, allowing connected inverters to draw or return energy as motion cycles demand. By performing this bidirectional power exchange, the unit supports energy-efficient operation in industrial automation cells that rely on dynamic servo axes, gantries, or handling modules. That operating role also helps smooth energy flow between accelerating and decelerating axes during rapid duty cycles.

This supply unit delivers a rated output of 15 kW, giving sufficient headroom for medium-power drive groups installed on assembly lines or packaging machinery. The DC bus nominal voltage is maintained at 700 V DC, which helps keep the intermediate circuit stable for predictable inverter operation and braking behavior. Thermal management is handled by internal air cooling with an integrated blower; the fan moves cabinet air across heat-sink channels to keep semiconductor temperatures within acceptable limits. For electrical safety, the housing meets IP20 protection, so it must be installed inside a closed control cabinet to avoid accidental contact with live parts. The power section uses a regenerative design, enabling surplus kinetic energy from decelerating axes to be pushed back to the mains instead of being dissipated as heat.

The unit is version 1 in series 02. It connects line power to the drive system and manages the shared DC bus for attached converters during acceleration and braking. Returned energy can be fed back through the supply stage instead of being turned into waste heat by separate braking hardware. This layout supports compact multi-axis cabinets where several drives share one stabilized bus.
