Product Description:

The HDS03.2-W075N-HA15-01-FW is a modular drive controller from Bosch Rexroth Indramat in the HDS Drive Controllers series. It is intended for multi-axis systems in automated production cells, where it coordinates power delivery to servo and spindle modules so velocity and torque follow programmed profiles during synchronized motion. Typical installations include assembly lines, packaging stations, and machining centers that use centralized cabinet-based drive hardware. The unit fits Indramat rack-style cabinets and supports modular layouts in which several control and power sections are arranged in one enclosure.

Its control loop accepts an analog reference through the Command Communication Interface, allowing velocity or torque setpoints to be delivered as ±10 V signals from a higher-level PLC or motion controller. The integrated cooling path uses a built-in air blower that circulates cabinet air across the heat sink, so external fans are not required for the controller itself. This airflow path helps remove heat during continuous operation and supports stable thermal performance inside the cabinet. The controller has a rated current of 75 A, which allows it to energize medium-power servo axes without saturation during normal operation. Because this current rating depends on the specified ambient conditions, supply transformers and cabling must be selected to match the unit's electrical load.

Within the DIAX04 family, the controller is part of Line 03 and is identified as Version 2. These identifiers indicate the product generation and layout used for this unit. They help distinguish this controller from other members of the platform that may use different interfaces, cooling arrangements, or current classes. The coding also places the module within the broader DIAX04 product structure used for cabinet-based drive systems.
