Product Description:

The HDS03.2-W075N-HA27-01-FW drive controller is produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as a closed-loop power stage that modulates motor current in automated machinery, accepting motion references from higher-level control hardware and delivering regulated torque to servo axes on assembly lines, packaging stations, and material-handling systems. Its purpose inside an automation cell is to convert low-level command signals into the precise electrical output required for repeatable speed and position performance. Used with a matching motor and feedback device, it helps maintain stable axis response during frequent acceleration, deceleration, and hold phases.

The controller exchanges setpoints through an analog command communication interface, so reference values arrive as continuous voltages rather than discrete fieldbus words. It is part of the DIAX04 family, which uses the same mechanical footprint and parameter structure across related axes. Thermal regulation relies on a built-in internal air blower; this fan pulls cabinet air across the heat sink to move waste heat without additional ducting. The power section is sized for a continuous motor phase output of 75 A. That current level suits medium-frame servomotors in continuous-duty automation axes when the unit is installed within its intended ambient temperature range.

Equipment selection details identify the unit as Line 03 and version 2. These codes correspond to this drive build and connector layout. Its classification as an HDS Drive Controller places it in multi-axis racks where several modules can power separate machine axes from one mains supply. The module is intended for coordinated motion systems that require regulated torque output and consistent response from axis to axis.
