Product Description:

The HDS04.1-W200N-HS55-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis machining centers or material-handling lines, the module serves as the power and control stage that converts DC-link energy into precisely regulated motor current and interprets velocity or position commands from the system controller. As an HDS Drive Controller, it pairs directly with HVE or HMS supply modules and shares a common diagnostic bus. That arrangement supports precise torque and speed response on axes that must accelerate, decelerate, and hold position under changing process loads. Because current regulation occurs inside the controller, the connected motor can follow commanded motion profiles with repeatable response across the axis.

Communication with the higher-level PLC is handled over the SERCOS fiber-optic interface, providing deterministic exchange of setpoints, status, and diagnostics. The unit belongs to the DIAX04 family, so it uses the same rack format and general operating structure found across that platform. A continuous output capability of 200 A equips it to operate large synchronous or asynchronous motors during rapid load changes without normal thermal derating. Heat is removed by a built-in air blower, and the circulating airflow keeps semiconductor temperatures within safe limits without external ducting. This cooling method supports dense cabinet layouts where direct heat removal at the heat sink is important for stable output.

The product is part of Line 04, which corresponds to this frame size, connector arrangement, and mounting pattern for DIAX04 racks. The drive controller is Version 1, indicating the product generation used for this controller type. The modular rack format keeps the power section separate from the supply section, which is typical for this class of multi-axis drive system. The separate supply module handles incoming power distribution, while the controller focuses on axis-specific current and feedback processing. This arrangement is suited for machine tools and automated handling equipment that group several drive axes in one enclosure.
