HDS03.2-W075N-HA24-01-FW
The HDS03.2-W075N-HA24-01-FW is a drive controller produced by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. Used in multi-axis machining centers and material-handling cells, it shapes current and voltage sent to attached motors so that commanded velocity and torque profiles are reproduced accurately inside automated equipment. It is also part of the DIAX04 family, which uses the same power bus connections and diagnostic structure across adjacent axes. That role allows the drive to support both servo axes and spindle applications that need repeatable speed and torque control during changing load conditions.
During continuous operation, the controller can deliver up to 75 A of output current, allowing it to energize mid-range servo or main-spindle units without derating. Control words reach the unit through an analog command interface, so velocity setpoints arrive as proportional voltage or current signals that the internal regulator filters and amplifies. Thermal management relies on a built-in air blower, which moves cabinet air across the heat sink to keep semiconductor junction temperatures within limits without external ducting. Because the cooling fan is integrated into the module, cabinet layout can remain compact while airflow is directed over the power section. This arrangement supports stable operation when the drive is used in coordinated motion systems that combine analog command signals with closed current regulation.
The unit is part of Line 03, so its control logic matches third-generation DIAX04 backplanes. It is also identified as Version 2, which uses updated gate drivers for higher pulse-width modulation fidelity. Within systems that still use analog velocity loops, the controller combines that command method with digital current regulation for accurate motor response. The updated gate-drive stage helps maintain cleaner switching behavior, and the mixed-signal layout remains compatible with installations built around analog command hardware.
