HDS03.2-W075N-HA42-01-FW
The HDS03.2-W075N-HA42-01-FW is a digital drive controller module manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In a multi-axis system, it serves as the power and control stage between the machine PLC and the connected servo axes. The module converts incoming supply power into regulated DC bus energy and forwards command signals through the drive system. This arrangement supports coordinated motion in packaging lines, machine tools, and automated assembly equipment where accurate axis response is required.
This version uses an analog command interface, so reference values are accepted as ±10 V input signals rather than through a networked control link. The power stage is rated for 75 A, allowing continuous current delivery to connected servo amplifiers without derating under its stated operating conditions. Cooling is handled by a built-in air blower that moves cabinet air across the heat sink, so no liquid circuit or external duct is required. As part of the DIAX04 platform, the unit matches the common backplane and shared DC bus arrangement used across that system. The combination of analog control and onboard power handling makes it suitable for applications that use conventional reference signaling instead of a digital motion bus.
The controller belongs to Line 03, which places it in the third design line of the platform. It is released as Version 2, indicating the second version of this product configuration. The module uses the standard mounting geometry and bus bar layout of the platform, which allows it to fit typical rack positions in multi-axis cabinets. Its place in the product range sits between lower-current and higher-current units when a machine requires mid-range output capacity on a shared DC link. This helps maintain a consistent cabinet layout while matching the current demand of the connected axes.
