Product Description:

The HDS03.1-W100N-HT71-01-FW drive controller is produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It functions as a modular axis unit that supplies regulated power and coordinated command signals to servo drives in automated machinery and production lines. By integrating power electronics and motion control functions in a single enclosure, the unit fits into multi-axis racks and supports synchronous operation across multiple axes in industrial automation cells. It is used where coordinated torque and speed control are required for machine axes in transfer systems, packaging stations, and handling equipment.

At the power stage, the controller can deliver a rated output current of 100 A, enabling high-torque acceleration of connected motors without external boosters. Command data reach the unit over the SERCOS fiber-optic ring, allowing cycle-synchronous setpoint exchange with the higher-level PLC. Within the DIAX04 family, this model uses the same rack format and interface arrangement as companion modules. Thermal management relies on a built-in air blower that draws air through the heat sink fins, which helps keep thermal loading under control during continuous operation. The unit operates in ambient air from +5 to +45 °C, and operation outside this range requires derating or shutdown protection.

The enclosure meets IP10 protection, offering basic guarding against solid objects while relying on the cabinet for additional sealing. Electrical insulation follows class C per DIN VDE 0110, which supports the internal temperatures associated with dense packaging. Operation is permitted up to 1000 m above sea level. Intermittent ambient peaks up to +55 °C can be tolerated with proportional current reduction. Storage is permitted from -30 to +85 °C when the controller is out of service.
