Product Description:

The HMV01.1R-W0120-A-07-FNN2 is a supply and regeneration module produced by Bosch Rexroth Indramat for the HMV IndraDrive Supply Units series. Acting as the central DC bus interface, the unit delivers regulated power to multiple drive controllers and returns excess kinetic energy to the mains during braking cycles. Within an automation cabinet, it supports high-power servo axes and converts three-phase input power into a stabilized bus voltage for packaging, printing, and material-handling systems. This arrangement lets several connected axes share one supply source while maintaining a common power link across the drive system.

Its bus circuit operates at a nominal voltage of DC 700 V, so connected inverters can share a common energy level without separate rectifiers. The module can source or sink up to 120 kW of continuous power for connected axes at rated duty. Because the power supply topology is regenerative, braking energy is returned to the plant supply instead of being dissipated in resistors, which reduces cabinet heat. This operating method is useful on machines with frequent deceleration of large moving masses. Cooling is handled by internal air cooling with an integrated blower, which forces airflow across the heat sink channels. The enclosure has an IP20 rating that helps protect against finger contact in filtered-air electrical cabinets.

The unit is design version 1 and series version 01, which place it within the current IndraDrive product line. Functionally, it is an HMV Supply Unit, so it is intended for the DC link position rather than for inverter duty. This version matches the connector layout used in current IndraDrive systems. The control electronics are arranged for use as the central power supply module on a shared bus, where several amplifiers depend on a stable common DC source during acceleration and braking.
