Product Description:

The HDS03.2-W075N-HS38-01-FW is a drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. As an axis module, it interfaces with servo motors and upstream coordinators to close current, velocity, and position loops within multi-axis industrial machinery. In a complete rack, this module supplies regulated power to a connected power section and executes motion commands from a higher-level automation system. This operating role supports precise speed and torque regulation in packaging lines, machine tools, and material-handling cells where several axes must respond together. The controller also manages rapid changes in commanded load so the connected motor can follow programmed motion profiles with stable response.

Communication with supervisory controls is handled by the SERCOS optical interface, allowing deterministic exchange of setpoints and feedback in real time. Because the controller belongs to the DIAX04 family, its bus connectors and diagnostic codes remain consistent with other axes in the rack. The optical link supports cyclic command transfer and feedback updates without electrical contact between the controller and supervisory system. Thermal management is provided by a built-in air blower that moves cabinet air across the heat sink, eliminating the need for external ducting and helping the power electronics maintain stable operating temperature. The power stage is rated for 75 A, and integrated functions include parameter storage, trace functions, and fault handling for routine axis operation.

Within the HDS Drive Controllers series, this module is part of Line 03. The unit is Version 2 and is identified as a Drive Controller. When linked to a central supply cabinet, it shares its DC bus with neighboring axes, uses the internal blower to maintain component temperatures, and exchanges synchronized position data over the SERCOS ring. Shared bus operation allows energy from one axis to be available to the rack during coordinated motion events. This arrangement lets the rack coordinate acceleration, deceleration, and steady-speed operation across multiple connected servo axes while keeping command timing aligned across the motion system.
