HDS03.1-W075N-HT02-01-FW
The HDS03.1-W075N-HT02-01-FW is a modular drive controller produced by Bosch Rexroth Indramat and placed in the HDS Drive Controllers series. Within multi-axis DIAX04 racks, the unit regulates torque, speed, and position of connected servo motors. It acts as the power and control interface between a higher-level PLC and each mechanical axis used in automated machining, packaging, or assembly stations. The module is intended for coordinated motion systems that require closed-loop axis control under centralized supervision. Its modular format lets it work alongside matching power components in a common rack system.
It communicates with motion supervisors over the SERCOS fiber-optic bus, allowing deterministic cyclic setpoints and diagnostic data. This bus supports synchronized command exchange across multiple axes in the same rack. The controller belongs to the DIAX04 family, which uses common mechanical dimensions and connector pinouts so it can slide into shared power-supply backplanes without rewiring. A continuous output capability of 75 A supports medium-power servomotor groups, while overload detection is handled internally by current sensors. Heat produced at that load is removed by a built-in air blower, so no external cabinet fans are required. The unit is part of Line 03 in the series.
The drive controller is Version 1. Within the platform, it uses standard encoder feedback formats, and its diagnostic LEDs match related modules, so status indication remains consistent across the rack. The unit supplies axis power, monitors fieldbus communication, and provides onboard parameter storage without separate interface cards. It can be used in single-axis retrofits as well as coordinated multi-axis cells without changes to the electrical footprint. These functions are built into the controller housing rather than being distributed across additional interface modules.
