HMS02.1N-W0028-A-07-NNNN-AA

The HMS02.1N-W0028-A-07-NNNN-AA is an axis inverter module produced by Bosch Rexroth Indramat for the HMS Axis Inverters series. Designed for integration in multi-axis collections, the unit forms the power stage that modulates the shared DC link energy for a single servo or induction motor. It receives command data from the higher-level controller and converts those instructions into accurately timed switching sequences, enabling coordinated velocity, torque, and position control across packaging lines, gantry loaders, and automated assembly cells.

In operation the inverter can deliver up to 28 A of output current, providing the necessary phase amplitude for medium-frame servo motors. It draws its energy from a common intermediate circuit at DC 700 V, so the upstream supply must keep that voltage within tolerance to prevent undervoltage faults. Thermal management is handled by a Internal Air with Integrated Blower system that circulates cabinet air across the heat sink without additional ductwork. The housing meets the IP20 protection class, permitting safe installation inside a closed control cabinet. Hardware marking identifies this unit as Design Version 1, the first release of this mechanical layout from Bosch Rexroth Indramat.

The control section carries no integrated auxiliary supply; it is explicitly listed as Not Equipped, so a separate 24 V source must power the logic and fan circuits. Firmware identifiers place the module in line version 2, ensuring parameter compatibility with other drives that share the same communication protocols and encoder evaluation standards. Classified under the HMS product type, the unit completes a modular drive stack by occupying a single slot, and its built-in blower discharges air through front louvers to limit cabinet temperature rise during continuous operation.
