Product Description:

The HDS03.2-W100N-HT25-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. It serves as a modular axis amplifier in multi-axis industrial motion systems, converting commands from a higher-level control network into regulated current for servo motors and closing the velocity and position loops in automated machinery. In a coordinated drive system, the unit works as the power stage between the central control and the motor. That arrangement helps the machine maintain commanded speed and position as load conditions change during operation. It is intended for use in automated machinery where multiple axes operate from a common control architecture.

This model communicates over the SERCOS fiber-optic bus, so cyclic setpoints and feedback travel on a real-time, noise-immune channel. Within the cabinet concept, the controller belongs to the DIAX04 family, which uses a common platform for compatible drive components. Thermal management relies on a built-in air blower; forced airflow through the heat sink keeps semiconductor temperatures within safe limits without external ducting. The power stage supplies up to 100 A of continuous motor current, allowing use with medium-to-high torque servo motors during demanding acceleration phases. The product is part of Line 03 in the platform, and Version 2 identifies the second functional revision of this controller.

The unit uses a shared backplane arrangement that supports compact cabinet layouts in multi-axis installations. It also uses pin-compatible bus and power connectors, allowing compatible axis cards to be installed on the same platform without changing the cabinet wiring scheme. As an HDS Drive Controller, it can draw power from common supply buses and return braking energy to the DC link rather than dissipating that energy as heat inside the cabinet. This helps limit added heat around adjacent modules during deceleration events.
