Product Description:

The HDS05.2-W300N-HA44-01-FW is a drive controller manufactured by Bosch Rexroth Indramat. As a modular axis controller, it is installed in DIAX04 racks to regulate the power stage of synchronous and induction motors used in machining centers, packaging lines, and material-handling systems. By converting command signals into precise current and voltage profiles, the unit coordinates speed and torque between multiple axes and the higher-level PLC. In multi-axis installations, it supports controlled acceleration, deceleration, and steady-state operation across connected drives. It can serve as the regulation stage where coordinated axis response is needed for synchronized feeds, indexing tasks, and load-dependent speed control in automated machinery.

This controller delivers a continuous output of 300 A. That is the maximum motor current the power section can supply without thermal derating. Commands reach the unit through an analog interface, allowing compatibility with legacy motion cards that send ±10 V velocity or torque references. A built-in air blower moves cooling air across the heat sink, which helps keep internal temperatures within an acceptable operating range during sustained load. The product is part of the DIAX04 family, and the unit is version 2 with updated gate-drive circuitry to reduce switching losses while retaining pin-for-pin compatibility with earlier models.

Mechanical designation Line 05 indicates the housing height and connector spacing so the unit fits adjacent modules without additional brackets. The unit continues the architecture of the HDS Drive Controllers series, which allows mixed-axis configurations with digital or analog command modules on the same bus. Its rack-based format also supports orderly integration with companion modules in the same drive assembly, helping maintain a consistent layout inside the cabinet.
