Product Description:

The HDS02.1-W040N-HS04-02-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Used within the DIAX04 automation platform, the unit provides regulated motor current and closed-loop axis control for servo or spindle drives on factory lines and machine tools. By processing motion commands from a compatible controller and modulating output current, it forms the electrical link between the higher-level motion system and the connected motor. This arrangement supports coordinated multi-axis operation in automated equipment.

Communication with the motion controller occurs over the SERCOS optical ring, enabling deterministic real-time exchange of command and feedback data. The power stage is rated to deliver 40 A of continuous output, which suits medium-frame servo motors under acceleration. Thermal management is handled by a built-in air blower that moves cooling air across the heat sink fins without external ducting. The housing has an IP10 rating, which protects against solid objects larger than 50 mm. Standard operation is specified for ambient temperatures from +5 to +45 °C, so the cabinet must stay within this range during sustained duty.

The controller may be installed at elevations up to 1000 m above sea level without current derating. When the surrounding temperature rises beyond the standard range, operation remains permissible until the air inside the enclosure reaches +55 °C, although output must then be reduced. For storage and transport, the electronics tolerate temperatures from -30 to +85 °C. Windings and internal wiring use the Class C insulation standard referenced in DIN VDE 0110, which supports thermal endurance during cyclic loading. The unit is Version 1 and matches the mechanical and electrical format used in the DIAX04 family.
