Product Description:

The Bosch Rexroth Indramat HDS05.2-W300N-HS12 is a drive controller from the HDS Drive Controllers series. Mounted on a common DC bus, it shapes three-phase output for matched servo motors and supports current, velocity, and position control in synchronized machinery such as pick-and-place units and process lines. The unit accepts centralized DC power from a supply module and can return regenerated energy to the same bus during braking. In automated lines, this allows the drive to manage rapid acceleration, controlled deceleration, and stable holding behavior under coordinated motion commands.

Thermal loading is managed by a built-in air blower that directs airflow along the heat sink fins, allowing full-load operation without external ducting. Command and diagnostic data reach the unit through the optical SERCOS interface, so real-time setpoints and status information travel on the same deterministic communication link. Inside the drive rack, the controller belongs to the DIAX04 family, and its power stage carries a continuous rating of 300 A. This current capacity allows the controller to energize large torque motors while staying within the di/dt limits imposed by winding insulation. The on-board gate array processes encoder feedback, samples current sensors at high frequency, and modulates the IGBTs to reduce overshoot during acceleration and regeneration.

The product is part of Line 05, which matches the mechanical width, connector pitch, and stack height used with compatible supply sections and auxiliary I/O cards. The unit is Version 2, identifying the release level used for this controller. Its module format keeps rack spacing and interconnection points consistent in high-power HDS assemblies. These characteristics support installation in systems that use matching power and interface modules on the same drive platform.
