Product Description:

The HDS03.2-W075N-HS58-01-FW is a digital drive controller from Bosch Rexroth Indramat. In a modular rack, it manages DC bus power and coordinates attached servo axes so higher-level controls can command torque and velocity with precision. Within multi-axis automation systems, it serves as the control stage that links drive hardware to PLC-based motion commands for synchronized positioning, feeding, and handling tasks. This lets machine tools, transfer systems, and material-handling lines execute coordinated motion without each axis operating as an isolated device.

This controller exchanges setpoint and diagnostic data through the SERCOS fiber-optic interface, which supports deterministic real-time communication around the drive ring. The optical link also helps isolate the command path from electrical noise inside cabinets that contain high-current switching devices. A continuous output capacity of 75 A allows the unit to support sizable servo modules without external current boosters. As part of the DIAX04 platform, it fits the mechanical slot layout used by related modules in the same rack. Thermal regulation relies on a built-in air blower, which pulls cabinet air through the heat sink to keep power semiconductors within their operating range during cyclic loads.

The unit is part of the HDS Drive Controllers series and is identified as Line 03 within that range. It is produced in Version 2, indicating the second hardware revision for this model. The product category is HDS Drive Controller, which places it in the standard controller class used for modular servo systems. These identifiers distinguish the controller variant used in racks where separate power sections and coordinated control channels are installed side by side. Its modular format suits cabinet arrangements that combine several axes on a shared DC bus while keeping each controller in a consistent slot position. The layout also supports orderly wiring between the control section, power stage, and external motion network.
