Product Description:

The HMS02.1N-W0028-A-07-NNNN-AA is an axis inverter module produced by Bosch Rexroth Indramat in the HMS Axis Inverters series. The module occupies one slot in a modular multi-axis drive stack, where it converts energy from the common DC link into regulated three-phase output for synchronous or asynchronous motors. In industrial automation, the device executes velocity and torque commands from a central motion controller, enabling coordinated movement in packaging machines, palletizers, and general material-handling axes. Because it operates within a shared drive system, the inverter performs motor-side power conversion at the axis level while higher-level coordination remains in the central control architecture.

Its power electronics are referenced to a nominal bus voltage of DC 700 V. The current path is rated for a maximum of 28 A, allowing the inverter to drive medium-capacity servo motors without overloading the output stage. The housing has an IP20 classification, so the unit must be installed inside a control cabinet that protects it from direct dust or fluid exposure. This cabinet-mounted arrangement separates the power stage from direct plant exposure and supports use in enclosed electrical assemblies. Thermal management uses internal air cooling with an integrated blower, which circulates cabinet air across the heat sink to remove switching losses. The unit comes without an internal low-voltage supply, so the logic circuits receive 24 V DC from an external controller or auxiliary supply rail.

The inverter is built as line version 2, which matches the second-generation control backplane used in this HMS platform. It is also design version 1, identifying the initial mechanical layout and connector arrangement for this rating class. These version codes distinguish the control format and mounting pattern used by the module.
