Product Description:

Bosch Rexroth Indramat developed the HDS03.2-W075N-HA20-01-FW drive module for multi-axis motion platforms that rely on closed-loop digital positioning. The unit belongs to the HDS Drive Controllers series and acts as a current-regulated power stage within a multi-axis servo system, where coordinated motion depends on accurate current delivery to each connected axis. It converts DC bus energy from a compatible supply module into three-phase output that follows velocity or torque commands, allowing servo motors to maintain precise speed regulation during indexing, handling moves, packaging cycles, and machining operations that require repeatable dynamic response.

The controller has a continuous output capability of 75 A, so servo axes drawing up to that current can be accelerated without derating. Thermal removal is handled by a built-in air blower, which directs airflow across the heat sink and supports stable operation under load without requiring a separate external cooling device for the module itself. Command data arrive through an analog command interface, which accepts ±10 V velocity or torque references from legacy PLC cards or motion boards and makes the controller suitable for systems built around conventional analog control signals. As part of the DIAX04 family, the unit uses the rack format and interface style shared by related axes in the same system, which helps keep module integration consistent across a multi-axis installation.

The product is part of Line 03, which identifies the design line used for its connector style and mechanical rack arrangement in compatible drive assemblies. The unit is Version 2, indicating the revision level assigned to this controller. It is classified as an HDS Drive Controller, so it operates with a matching supply module and motor feedback card rather than as a standalone power converter, and it is intended for coordinated servo installations that use a shared DC bus architecture.
