Product Description:

The HMS02.1N-F0054-A-07-NNNN is an axis inverter produced by Bosch Rexroth Indramat in the HMS Axis Inverters series. In multi-axis automation cells, it serves as the intermediate power stage between a common DC bus and individual servo or spindle axes. It converts stored bus energy into controlled motor current so coordinated moves, acceleration ramps, and speed changes can be carried out with consistent timing. Because the DC bus is shared across the machine, the inverter can participate in a centralized power structure that supports coordinated axis operation.

This model uses liquid cooling, so heat from the switching section is removed through a closed coolant circuit instead of relying on cabinet air. The enclosure has an IP20 rating, which means the unit is finger-safe but still intended for installation inside a protected control cabinet. Under continuous operation it can deliver up to 54 A of rated output current, providing capacity for medium-power feed axes and similar motion tasks. The inverter operates from a shared bus of DC 700 V, which supports energy exchange between accelerating and braking axes on the same drive system. By moving heat into the coolant path, the module helps reduce the thermal load placed on the cabinet interior.

The unit is identified as Design version 1, indicating the established build for this model. It is also listed as Line version 2, placing it in the second line version used for this product platform. The inverter has no internal power supply, so control-side power must be provided by the connected system. That arrangement matters when the axis module is paired with upstream supply electronics, because auxiliary power is handled outside the inverter rather than generated within the unit. This keeps the module focused on power conversion and motion output while system-level supply functions remain in separate hardware.
