Product Description:

The HDS03.1-W100N-HS33-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series used in multi-axis industrial automation racks. In a DIAX platform, it acts as the power and control stage between the supply section and individual motor drives. This arrangement supports coordinated motion on production lines and machining centers while allowing the higher-level machine control to send axis commands and receive diagnostic information. Installed within a shared rack, it supports synchronized servo motion for indexing, feed movement, and other repeatable machine cycles.

The controller exchanges real-time setpoints and status words over the fiber-optic SERCOS interface, enabling deterministic communication with numerical controllers. The optical link helps maintain reliable data transfer in cabinets that also contain high switching currents. It belongs to the DIAX04 family, so its mechanical dimensions match other fourth-generation DIAX components. Thermal management relies on a built-in air blower that moves cabinet air across the heat sink without external ducting. Continuous output of up to 100 A supports high-torque servo axes, and the power stage is identified as Line 03 within the product code.

The unit is Version 1, which identifies the product generation for this controller. As a command and power interface, it relays diagnostic data to upper-level PLCs and works with the rack to support closed-loop motion functions. Cooling airflow passes across the internal heat sink to help keep the power semiconductors within normal operating temperature during rated duty cycles in densely packed electrical enclosures. The controller combines communication, axis regulation, and power handling in one module, which reduces the need for separate external cooling components around the drive section.
