HDS05.2-W300N-HA26-01-FW Bosch Rexroth Indramat

Product Description:

The HDS05.2-W300N-HA26-01-FW is a modular power and control unit produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Acting as an axis drive controller, it links a supply module to synchronous or induction motors and executes torque, speed, or position loops in automated machinery. The device forms part of DIAX04 multi-axis racks, where it serves as the intermediary between motion commands received from higher-level PLCs and the motor power stage.

Electrical capability is defined by a continuous output of 300 A, enabling the controller to handle large-frame motors without external booster cards. Motion references arrive through an ANALOG interface, so voltage or current set-points can be generated directly by legacy control systems or modern converters with minimal protocol conversion. Thermal management relies on a Built-in Internal Air Blower that directs airflow across the IGBT heatsink, keeping cabinet temperature rise low during sustained operation. Belonging to the DIAX04 controller family guarantees shared parameter structures and firmware tools across the platform, while Line 05 indicates the fifth-generation power design that incorporates faster gate drivers and reinforced bus bars. No alternate mechanical or electrical variants are listed for this catalog code, simplifying selection for retrofit projects.

Firmware released under suffix ‑FW must match Version 2 hardware so that diagnostic registers align with updated sensor layouts. Technical service catalogues issued by Bosch Rexroth Indramat classify the unit as an HDS Drive Controller, streamlining spare-parts logistics for service centers. With no alternate versions, the drive is supplied as a single defined hardware package, reducing inventory complexity. The control board measures bus rail potential and phase currents, relaying real-time status to adjacent modules through a back-plane link. Continuous diagnostics monitor switching losses and airflow, triggering derate routines before thermal thresholds are reached. When assigned as a driving axis in a multi-module rack, its firmware can scale current loops to match motor inductance without altering cabinet ventilation or wiring routes.
