HDS03.2-W075N-HS93-01-FW
The HDS03.2-W075N-HS93-01-FW is an axis controller manufactured by Bosch Rexroth Indramat for a modular drive controller platform. Within the DIAX04 motion system, the module regulates torque, speed, and position on connected servo axes in automated machines and production cells. It supplies controlled DC-link energy to the motor circuit and exchanges command data with higher-level controls, making it the link between the drive power section and the machine control layer. By separating the axis controller from the supply section, the system supports a flexible cabinet layout for multi-axis assemblies. This arrangement is suited for machines that require coordinated motion during feeding, indexing, cutting, or transfer movements.
The controller communicates with the motion control network through SERCOS over a fiber-optic ring, allowing deterministic command exchange and real-time status reporting. Using an optical link also helps reduce susceptibility to electrical noise inside industrial control cabinets. Continuous output is limited by a rated current of 75 A, so the connected drive section and motor application must stay within that operating range. Thermal management is handled by a built-in air blower that moves cabinet air across the heat sink without external ducting. The unit follows the DIAX04 platform layout, and it is part of Line 03 in this controller family.
The unit is Version 2 and is described as an HDS Drive Controller. It works with matching power sections and supply units across the HDS Drive Controllers platform, so it can be integrated into multi-axis drive assemblies that use the same module format. The controller keeps the established parameter structure used for this product group while supporting the communication and control tasks expected from the series. Its modular format also helps maintain a consistent mechanical footprint and connector arrangement within the cabinet. That consistency can simplify layout planning when several adjacent drive modules are installed in the same enclosure.
