Product Description:
The HMS02.1N-W0054-A-07-NNNN is an axis inverter manufactured by Bosch Rexroth Indramat as part of the HMS Axis Inverters series. In a multi-axis drive package, it modulates DC-link energy from a central supply unit and delivers controlled three-phase output for synchronous or induction motors. This arrangement allows a shared supply to feed several axes while each inverter regulates the motor connected to its own output stage. It works with closed-loop control to support accurate speed and torque regulation on coordinated machine axes. The device is installed in a control cabinet, where it serves as the power section of closed-loop motion systems used in material handling, packaging machines, and general automation.
The inverter uses internal air cooling with an integrated blower, so airflow moves through the housing and across heat-producing components without external fans. A nominal DC bus of DC 700 V links the inverter to the common supply, providing the voltage margin needed for high-speed servo axes and shared DC-link installations. Motor windings can draw up to 54 A of phase current, which is the continuous thermal load that the power section and cabinet ventilation must accommodate during operation. The enclosure is rated IP20, so it guards against finger contact with live parts and is intended for cabinet installation rather than exposed mounting. Its parameter structure and communication interfaces align with other controllers in the same platform, which helps keep multi-axis systems consistent.
The unit is in design version 1, which places it in the first mechanical release of this platform. It is also in line version 2, which matches the control wiring and fieldbus options used with second-generation IndraDrive accessories. The inverter is supplied without an internal power supply, so logic and brake control voltages must come from external sources. This arrangement fits cabinets where auxiliary supply functions are provided by separate system modules.
