Product Description:

The HMS02.1N-W0054-A-07-NNNN-AA is an axis inverter module produced by Bosch Rexroth Indramat as part of the HMS Axis Inverters series. It converts energy from a shared DC bus into regulated three-phase output for servo-driven industrial axes, allowing connected motors to receive the voltage and current needed for controlled motion. The module is intended for coordinated motion systems in which several inverter sections operate from a common power stage. This layout is typical in compact machine cabinets that group multiple axes around one central supply section.

The inverter has a rated maximum current of 54 A, which allows it to control motors that require high continuous torque during acceleration and steady running. Its common bus operates at a nominal DC 700 V, so it must be connected to a compatible supply or regenerative power section rather than a standalone low-voltage source. Heat is removed by internal air cooling with an integrated blower, which moves cabinet air across the heat sink to carry away switching losses during operation. The enclosure rating is IP20, so the module is intended for installation inside a control cabinet where live parts remain protected from accidental contact. Because the airflow stays inside the cabinet, surrounding panel ventilation must allow the blower path to remain unobstructed.

The unit is Design Version 1 and uses Line Version 2 for its interface and control format within the drive platform. It relies on an external 24 V logic supply because it is not equipped with an internal power supply, and the DC link capacitance is provided by the shared power section instead of inside the inverter. The product uses the HMS type code, which places it within Rexroth's modular inverter range for multi-axis systems. In this arrangement, the inverter section focuses on motor output while the supply module provides the shared bus support for the connected axes.
