Product Description:

The HDS03.1-W100N-HA16-01-FW is a motion control module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It operates as a power stage that converts command signals from upper-level control hardware into precisely regulated current, allowing multiple servo axes to accelerate, decelerate, and hold position with predictable dynamics. In automated transfer lines, press feeds, and robotics cells, the unit forms the interface between the central PLC and the motors, ensuring coordinated movement while protecting the drive train from overloads.

The device belongs to the DIAX04 controller family and communicates with the master through an ANALOG command interface, so velocity or torque references are carried as ±10 V signals rather than digital fieldbus frames. Its nominal output capability is a rated current of 100 A, which defines the continuous motor phase current it can deliver without derating. Thermal control is handled by a Built-in internal air blower that draws cooling air across the heat sink, allowing the controller to maintain this current even when installed in densely populated cabinets. The hardware's electrical section remains isolated from control electronics, and system wiring for power, feedback, and blower supply is routed on a single front panel to streamline installation.

The module is catalogued as line 03, revision 1, meaning its circuit board layout and firmware connector set match the earliest production release. With no alternative configurations available, the “Other Versions” entry is listed as None, simplifying replacement logistics. Within the assembly hierarchy it is classified as an HDS Drive Controller, so commissioning software recognises it automatically and applies parameter limits that correspond to its power stage and cooling profile.
