Product Description:

The HMS02.1N-F0110-A-07-NNNN is an axis inverter produced by Bosch Rexroth Indramat in the HMS Axis Inverters series. As an inverter, it converts shared DC-bus energy in a multi-axis system into regulated three-phase output for servo motors, enabling coordinated speed and torque control on production machinery, material-handling gantries, and packaging lines. This role allows it to coordinate motion with other axes on a common power platform where several servo motors operate together. The IP20 housing provides finger-safe protection for internal electrical parts, but it still requires installation inside a control enclosure because the rating does not protect against dust buildup or fluid ingress.

This model employs liquid cooling, so heat is carried away through a closed coolant circuit instead of depending on ambient air inside the cabinet. This cooling method helps reduce thermal loading around neighboring modules in dense enclosures. The internal power section operates from a nominal DC link of DC 700 V, a level commonly used for high-performance servo systems that need rapid current response. When commanded, the unit can deliver phase current up to 110 A, which supports larger motor loads and stronger acceleration demands. The electronics use design version 1, indicating the first release of this HMS platform variant.

The unit is in line version 2, which is compatible with second-generation mains and DC-bus interfaces used in newer Rexroth cabinets. For auxiliary circuitry, it is not equipped with an internal power supply, so 24 V control power must be supplied from an external source before the inverter can enable its gate drivers and supporting electronics. External control power also allows the logic circuits to start before the main power stage is enabled. The product descriptor HMS groups this model with related motion inverters that share the same parameter structure and diagnostic approach.
