Product Description:

The HDS03.1-W075N-HA03-01-FW is a modular drive controller from Bosch Rexroth Indramat that belongs to the HDS Drive Controllers series. It operates within the DIAX04 automation platform, supplying regulated DC bus energy and coordinating axis commands for multi-axis machinery. In industrial equipment, the unit forms the power and control interface between the main supply and the servo motors, allowing coordinated motion profiles, current limiting, and fault monitoring for packaging lines, printing presses, and material-handling systems. This arrangement supports synchronized axis behavior while helping the connected motors respond consistently to changing load conditions.

This controller can deliver a continuous output of 75 A, which indicates the maximum motor phase current the unit can regulate without thermal derating. Command signals are accepted through an analog interface, so velocity or torque references can be provided as ±10 V levels from a PLC or motion card. Heat produced by switching devices is removed by a built-in internal air blower, eliminating the need for separate cabinet fans. Reliable operation is maintained across an ambient range of +5 to +45 °C, although higher surrounding temperatures can require current reduction. The housing carries a protection rating of IP10, which provides basic guarding against accidental contact but no water protection, and the power sections use insulation class C materials that tolerate elevated operating temperatures.

Additional limits apply to installation and storage conditions. The unit is specified for mounting up to 1000 m above sea level, where reduced air density still allows the blower to cool internal components. This altitude limit helps maintain predictable cooling performance during normal installation. Short-term operation is permissible up to +55 °C with proportional current derating, which supports brief operation during hotter production periods. When the machine is shipped or warehoused, components remain intact between -30 to +85 °C, so typical transport and storage temperature swings do not damage the insulation system or electronic assemblies.
