HDS03.2-W075N-HT74-01-FW
The HDS03.2-W075N-HT74-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Mounted on a shared DC bus, it converts digital motion commands into controlled three-phase current for connected motors. In automated systems, this allows the module to regulate torque and speed for conveyors, pick-and-place axes, and machining spindles. Its modular format suits multi-axis cabinets where several drives operate from the same power structure. Because it works from a common bus arrangement, multiple axes can be integrated in one cabinet layout without separate power conversion stages for each motor channel.
The unit exchanges command and feedback data over the SERCOS interface, allowing deterministic communication between the motion controller and the drive. A continuous output rating of 75 A indicates the phase current the module can supply during steady operation without thermal derating. As part of the DIAX04 platform, it uses the same basic mechanical format and rack integration style as related modules in the system. Heat from the power stage is removed by a built-in air blower, so external ductwork is not required for normal cabinet installation. Deterministic timing is useful when several axes must follow coordinated motion profiles with consistent response.
The product is part of Line 03 and is listed as Version 2. It uses nonvolatile memory cards to retain operating data when power is removed, which helps preserve axis settings between machine restarts. When the module is connected in a closed fiber-optic ring, synchronized data exchange supports stable coordination between axes during dynamic motion. This controller links the shared supply rail to the motor leads inside a rack-based drive system and is intended for precise closed-loop operation in industrial automation. Its operating role centers on accurate current delivery and repeatable response during frequent acceleration and deceleration cycles.
