Product Description:

The HMV01.1R-W0018-A-07-FNN1 is a supply module produced by Bosch Rexroth Indramat for the HMV IndraDrive Supply Units series. Within an IndraDrive multi-axis system, this unit converts line power into a regulated DC bus and returns excess kinetic energy to the grid during braking. In automated cells, it forms the central power interface that feeds multiple inverter modules. This arrangement supports shared bus operation and reduces wasted heat during deceleration, especially when several axes brake at different times.

This supply module delivers a rated output of 18 kW, providing sufficient bus power for medium-sized servo groups. The internal link voltage is maintained at DC 700 V, a level matched to IndraDrive inverters so that motor torque response remains stable across load changes. Thermal management uses internal air cooling with an integrated blower; air is drawn through the electronics and expelled without external ducting, which helps keep cabinet layout straightforward. The housing is rated IP20, so it is intended for closed control panels where no liquid ingress is expected. The power section supports regenerative operation, which sends braking energy back to the line instead of dissipating it in resistors. This also helps limit extra heat buildup inside the cabinet during repeated braking cycles.

The enclosure and control boards correspond to design version 1, which identifies the unit’s design release. It is also listed as series version 01, matching the initial production revision for this model. In an IndraDrive cabinet, the module supplies several servo amplifiers from one power section, which keeps the power path centralized and consistent across the drive group. These connected axes operate from a common DC link, allowing the supply module to support coordinated multi-axis motion with one shared energy source.
