Product Description:

The HDS03.2-W075N-HA07-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within an automated axis system, the unit supplies regulated power to servo drives and links motion commands from the higher-level PLC to the motor inverter stage. By combining control electronics, the power section, and cooling in a single housing, the module provides closed-loop current and velocity regulation for multiaxis packaging, material-handling, or machining cells. In operation, it bridges higher-level machine commands and low-level drive control so the connected motor can follow commanded speed and current values.

The command communication interface is analog, so the controller expects proportional ±10 V speed or torque references along with enable signals. This allows straightforward integration with legacy PLC cards that output analog voltages. It is part of the DIAX04 controller family, so its parameter structure, diagnostic codes, and SERCOS bus expansion follow that platform. Thermal management uses built-in cooling with an internal air blower that draws cabinet air through the heatsink fins, eliminating the need for external ducting. The power stage is rated for 75 A, allowing the module to process continuous motor RMS current without derating and to support medium-to-large synchronous or induction servomotors in cyclic duty.

The device is Version 2, which indicates a second-generation design with updated gate drivers and faster signal processing than the earlier release. It uses 03 line width within the DIAX rack, so it shares mounting hole positions and connector locations with other controllers of the same frame size. The consistent mechanical format helps the unit fit standard rack layouts where matching controller widths are required.
