HDS03.1-W075N-HA12-01-FW
The HDS03.1-W075N-HA12-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is designed for installation in a DIAX04 multi-axis drive rack, where it supervises power modules and servo feedback so each axis receives the commanded torque or velocity reference. Within the rack, it manages the relationship between the power section and incoming control signals so connected axes can respond predictably during acceleration, speed regulation, and positioning tasks. In machine-tool, packaging, and material-handling equipment, the unit links motion drives to higher-level control systems and supports synchronized motion across multiple axes.
Its command channel uses an analog interface that accepts ±10 V reference signals for torque or velocity control, allowing continuous commands to be translated into real-time servo action. Because the input is analog, the controller can follow external command sources that send proportional control voltage rather than digital network commands. The unit can deliver up to 75 A of regulated current for medium-power axes without derating under the stated rating. Thermal management is handled by a built-in air blower, so heat is carried away through the aluminum heat sink instead of depending on separate cabinet airflow. The controller also includes parameter memory, diagnostic LEDs, and wiring terminals that match the standardized rack layout.
The module is part of Line 03 and is released as Version 1. These identifiers indicate the product generation used for this controller type and distinguish it from other layouts in the same product line. The model code also separates controllers by cooling method, current class, and command interface, so this unit is grouped with air-cooled controllers that use analog input control. That coding helps keep the controller aligned with compatible rack components and interface arrangements used in the same drive system.
