HDS03.2-W075N-HS
The HDS03.2-W075N-HS is a modular servo drive controller produced by Bosch Rexroth Indramat. Within an automation cell, it functions as the power and regulation stage for synchronous or induction axes. It converts DC-bus energy from a shared supply into controlled three-phase output so connected motors can follow torque, speed, and position commands from a CNC or PLC. In multi-axis motion systems, the controller regulates motor current so acceleration and steady-speed operation remain stable under changing loads. Its modular format suits cabinets where several drives operate from a common power structure.
This unit delivers a continuous output of 75 A, so a single controller can energize medium-torque motors without external current boosters. Communication with the motion coordinator is handled over the SERCOS fiber-optic bus, which transfers command values and feedback data in real time through a single loop. The fiber-optic link also supports synchronized data exchange between the controller and the higher-level motion system. Thermal management relies on a built-in internal air blower that draws cabinet air through the heat sink to keep semiconductors within their temperature limits. The hardware platform belongs to the DIAX04 controller family, which uses a common connector layout and consistent diagnostic routines across related modules.
The unit is Version 2 and part of Line 03. These identifiers indicate the product generation and its place within the established hardware line. It is part of the HDS Drive Controllers series and interfaces directly with Indramat modular supplies through shared DC link terminals. The shared DC link arrangement allows power from a common supply module to be distributed to adjacent drive units in the same rack. This layout supports coordinated operation in modular drive cabinets and keeps the electrical connection scheme consistent across matching system components.
