Product Description:

The HDS03.2-W100N-HS80-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In an automation cell, it acts as the axis amplifier between the motion control CPU and the connected servo motor. It closes the current and velocity loops while converting command data into controlled motor power. This arrangement lets the higher-level controller manage the machine path while the drive handles the fast regulation needed for repeatable axis movement. Because regulation takes place inside the controller, the connected motor can respond quickly to load changes during acceleration and deceleration. The module is intended for servo applications where steady velocity control and accurate following behavior are required over repeated cycles.

The controller delivers a continuous output of 100 A, enabling it to energize medium-to-large servo motors without external boosters. Motion commands reach the unit through the fiber-optic SERCOS interface, allowing deterministic communication and daisy-chain wiring across multiple axes. Thermal energy generated by switching devices is removed by a built-in air blower, so airflow stays focused around the heat sink inside the cabinet. The fiber-optic connection also reduces susceptibility to electrical noise in cabinets that contain high switching currents. The product is part of Line 03 and is marked as Version 2. These identifiers indicate the design revision used for this controller.

This HDS module is part of the DIAX04 controller family, so it slides into a multi-axis rack alongside the platform's supply and logic sections. Within that rack, it works as the power stage for a servo axis and supports coordinated operation with neighboring modules. Its rack-based format keeps power conversion, control interfacing, and axis expansion within the same drive platform. Classified as an HDS Drive Controller, the unit is suited for machining centers, packaging equipment, and handling systems that depend on accurate motion response. That layout is useful in compact systems where several servo axes must be coordinated from one control architecture.
