Product Description:

The HDS03.2-W075N-HS41-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. It serves as a modular axis module that supplies regulated power and motion commands to Indramat servo drives within automated systems. In industrial automation cells, it acts as the intermediary between a higher-level PLC and the motor power stage, coordinating torque, speed, and position loops through real-time digital communication. That arrangement allows the control system to send command values while the controller manages the electrical response needed for precise axis movement on packaging, handling, and general production equipment.

This controller exchanges process data over SERCOS, a fiber-optic ring that provides cyclic setpoints and feedback with deterministic timing rather than variable network delays. The optical link supports synchronized command exchange between the control system and the axis electronics when several drives must follow coordinated motion. It belongs to the DIAX04 family, so it shares a common platform and mechanical format with other axis modules in that system. Thermal management is handled by a built-in air blower, which directs heat out through the unit's heatsink channels and supports stable operation during sustained electrical load. For motor groups that draw significant energy during acceleration, the module has a continuous output current of 75 A under nominal ambient conditions.

Within the product range, the unit is assigned to Line 03, placing it in the third design line of this controller platform. It is built as Version 2, which marks the second revision of the component layout while keeping the same external format. These identifiers distinguish the controller from earlier revisions in the same range. They also help separate this unit from similar modules when several axis controllers are installed in one drive cabinet.
