Product Description:

The HDS05.2-W300N-HS79-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as the power and control stage for servo axes, supplying regulated current to connected motors while exchanging motion commands with higher-level PLCs. By coordinating velocity, torque, and position loops, the unit supports precise multi-axis motion in packaging lines, machine tools, and material-handling systems. The controller continuously adjusts motor current in response to command changes and load variation, which helps connected axes hold programmed motion profiles during acceleration, steady running, and stopping.

At the communication layer, the unit implements the SERCOS fiber-optic interface, allowing deterministic cyclic data exchange with central motion controllers. Its nominal output capability reaches 300 A, so inverter stages paired with large servo motors can accelerate demanding loads without current starvation. Thermal energy generated at that level is removed by a built-in air blower, which supports heat sink cooling without external ventilation ducts. The controller belongs to the DIAX04 platform and is part of Line 05, placing it within the corresponding design line of the series. In this platform, it uses standardized backplane connectors and shared supply modules across the system, which helps it integrate with companion modules.

The product is Version 2. It operates as an HDS drive controller that accepts shared DC-bus power from an HVE supply unit. During deceleration, regenerated energy returns through the same DC link instead of requiring a separate power path. This arrangement supports compact multi-axis systems where several controllers draw from one common supply section, and each unit manages the motor-side current regulation for its assigned servo axis.
