Product Description:

The HDS05.2-W300N-HA40-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It occupies one slot in a modular rack and delivers regulated armature current to servo or spindle motors used in machining centers, packaging lines, and transfer stations. By translating command references into precise pulse-width-modulated outputs, the module forms the active link between the motion control CPU and the mechanical axis. This arrangement supports centralized multi-axis systems where power modules and control electronics are grouped in a common enclosure. Its Euro-card housing and front-access connectors keep connections reachable from the rack face without disturbing adjacent hardware.

The unit has a continuous output capability of 300 A, allowing it to energize high-torque drives without auxiliary amplifiers. Command references arrive through an analog command channel, so ±10 V velocity or torque signals can be wired directly from classic PLC motion cards. Thermal management is handled by a built-in air blower, which moves cabinet air across the heat sink to maintain semiconductor temperature during rapid acceleration cycles. The controller belongs to the DIAX04 family, so it uses the platform’s standardized backplane connections for fiber-optic feedback and shared DC bus operation. The designation 05 in the type code marks the highest current class in the HDS range and pairs the large output stage with reinforced power tracks and heavier bus bars.

The unit uses hardware revision 2, which includes gate-drive refinements that support the switching frequencies required by the large current path while keeping the pin assignments unchanged. It installs directly beside matched supply modules in the same rack and does not require custom brackets. The unchanged pin assignments preserve the established wiring layout within compatible racks. The fixed configuration keeps the cooling arrangement and interface layout consistent within this model. It is used in rack-based systems with shared bus connections and matched power sections.
