Product Description:

The HDS03.2-W100N-HT20-01-FW belongs to the HDS Drive Controllers series manufactured by Bosch Rexroth Indramat. As a drive controller, it serves as the central regulating element between a DIAX04 power module and connected servo or spindle motors in an automated cell. Within an industrial automation line, the unit modulates torque and velocity commands so that connected axes follow the motion profile issued by the machine control. In this position, it links power conversion with closed-loop motor control rather than acting as a standalone supply unit. This role makes it suitable for coordinated motion where accurate response to command changes is required across multiple axes.

This controller exchanges cyclic setpoint and feedback data through the SERCOS fiber-optic interface, allowing deterministic communication with higher-level PLCs. A continuous output capability of 100 A supports medium-power servo channels that draw high dynamic current during acceleration. Thermal energy created by switching losses is removed by a built-in air blower, and the airflow passes across heat sink surfaces without external ducting. Compatibility with the DIAX04 multi-axis family means the device slides onto the common backplane and shares a DC bus with neighboring drives. The designation Line 03 identifies the product line used for this controller.

The controller is Version 2. It is classified as an HDS Drive Controller, so its regulation loops, diagnostics, and safety interlocks suit machining centers and material-handling systems. The module format matches the rest of the product line, which helps it fit into multi-axis installations that use the same mechanical platform. Its control functions are intended for industrial automation systems that require coordinated motion and stable axis response during continuous operation.
