HDS03.1-W075N-HA13-01-FW
The HDS03.1-W075N-HA13-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Within a multi-axis system, it supplies regulated power and feedback handling for servo axes, allowing machine tools and material-handling stations to execute coordinated motion sequences. By converting higher-level speed and torque commands into timed current patterns, the unit forms the link between control logic and the electromechanical load. Its modular format suits cabinet-based automation systems that separate power supply, control, and motor connection functions across coordinated hardware. This helps individual axes respond predictably during indexing, feed control, and synchronized transfer tasks.
The controller uses an analog command interface, so it can process reference signals such as ±10 V and convert them into pulse-width-modulated output for the connected drive section. A continuous output capability of 75 A supports medium-power axes without requiring a parallel amplifier, which helps keep the system layout compact. Thermal stability is maintained by a built-in air blower that moves cabinet air through the heat sink and exhausts it upward. The unit is part of the DIAX04 family, so its connectors, diagnostics, and parameter structure remain consistent with other modules in that platform. This arrangement supports stable operation where accurate speed control and repeatable torque response are required over long production runs.
The unit is Version 1 and part of Line 03 in the product range. It also uses detachable terminal strips, which keep control wiring accessible and simplify front-side connection work inside the cabinet. Standard fault LEDs show operating status and active fault conditions during use. The controller fits multi-axis installations where orderly module layout and direct status visibility are important. Its front-access connection style supports clear wiring paths without adding external interface hardware.
