Product Description:

The HDS05.2-W300N-HT05-01-FW is a drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a modular main unit, this controller supplies and manages power to matched servo drives in multi-axis DIAX04 racks. In industrial automation, it executes axis command data, modulates current, and enforces protection routines so connected motors can follow motion profiles under closed-loop control. Its modular format supports rack-based systems where several axes operate from a shared power structure and coordinated control architecture.

The power section is dimensioned for a continuous bus current of 300 A, enabling use with medium-to-high torque servo motors without external boosters. Command data reach the unit through the SERCOS fiber-optic interface, allowing deterministic cycle times and electrical isolation from control cabinet wiring. As part of the DIAX04 family, it uses standardized parameter lists so axis modules in the same rack share identical telegram structures. Thermal management is handled by a built-in air blower, which draws cabinet air through dedicated channels and helps prevent heat accumulation on the IGBT stack. The device is part of Line 05, so common power and signal backplanes align with that generation's mechanical footprint.

The drive is Version 2, with updated gate-drive circuitry and diagnostic registers compared with the initial release. The unit is an HDS Drive Controller, and installation parameters such as DC bus voltage, encoder evaluation slots, and fault relay wiring follow the same product group. This keeps the controller aligned with the slot assignments and electrical connection scheme used in the rack. The part number suffix indicates a firmware-related option, but the controller hardware remains unchanged in its main operating role.
