HDS03.2-W075N-HA13-01-FW
The HDS03.2-W075N-HA13-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Installed in multi-axis cabinets, the unit accepts motion references from higher-level CNC or PLC equipment and modulates current for individual power sections. This allows precise torque, speed, and position control of connected servo motors in automated machining and material-handling systems. In normal operation, it processes command and feedback signals for coordinated axis motion during interpolation, indexing, and speed-controlled movement.
This controller exchanges setpoint and feedback data through an analog command interface, so drive commands are carried by differential voltage levels rather than a digital network. Because the interface is analog, the controller can be paired with systems that use conventional voltage-based command signals instead of optical or Ethernet communication. Thermal management is provided by a built-in air blower that moves cabinet air across the heat sink and helps maintain stable internal temperature. The power electronics are rated for a continuous output of 75 A, which is the maximum RMS motor phase current available under nominal conditions. The unit is Version 2 and uses updated control circuitry and diagnostic LEDs while remaining compatible with earlier modules in the same platform.
It is part of the DIAX04 family and uses the rack layout and connector arrangement intended for that platform. The unit is part of Line 03 in the series, and its dimensions match 75 mm supply sections and the associated bus bars used in the cabinet. That compatibility supports orderly power distribution when several axes share common mounting rails in one control enclosure. The controller can be installed where consistent mechanical spacing is required between adjacent modules.
