Product Description:

The HDS03.2-W075N-HS33-01-FW is an axis module in the HDS Drive Controllers series from Bosch Rexroth Indramat. It works as the power and control stage for one motion axis, converting DC bus energy into regulated motor current while responding to speed and torque commands from the drive system. It installs beside a suitable supply unit and servo motors to regulate motion in machine tools, material-handling gantries, and high-speed packaging equipment. The module operates with a supply unit on the common DC bus, which allows several axes to share centralized power distribution and braking energy handling within the same drive platform.

Command and feedback traffic reaches the module through the industrial fiber loop used by SERCOS, allowing deterministic position updates at each interpolation cycle. Deterministic communication is important when several axes must stay synchronized during contouring, transfer, or indexing tasks. Electrical and mechanical dimensions align with the DIAX04 multi-axis rack, so the module fits system layouts that use matching power and interface units. The power stage can supply up to 75 A of continuous motor current, providing headroom for medium-frame servo drives during frequent acceleration and deceleration. This arrangement lets the controller manage motor current directly while higher-level commands continue to arrive over the optical network.

Thermal stability is maintained by a built-in air blower mounted in the housing, so no external ducting is required when the unit operates in a sealed cabinet for continuous production. Forced airflow across the heat sink helps remove heat from the power semiconductors during sustained load periods. The unit is part of Line 03 and is Version 2. Those identifiers indicate the product generation used for this controller and distinguish it from other releases in the same platform.
