Product Description:

The HDS03.1-W100N-HT14-01-FW is a drive controller manufactured by Bosch Rexroth Indramat. In automated machining, printing, and material-handling lines, it converts motion commands into precise current and voltage profiles for connected servo or spindle motors. By providing closed-loop regulation and diagnostic functions, the module helps maintain axis accuracy, limits unnecessary mechanical stress, and supports coordinated movement across complex industrial cells. Its modular format also allows it to slide into a standardized backplane that shares power and logic with neighboring components. That arrangement keeps the controller integrated with other rack modules while preserving a compact cabinet layout.

The control section exchanges real-time data over the SERCOS protocol carried on a fiber-optic ring, so setpoints and feedback travel with deterministic timing. This communication method supports synchronized command updates between the controller and the higher-level motion system. It is part of the HDS Drive Controllers series within the DIAX04 platform, which supports rack-based multi-axis layouts with shared power and logic connections. A silicon IGBT bridge supplies up to 100 A of continuous armature current for connected servo or spindle motors. Heat generated by the switching devices is removed through a built-in air blower, so the unit does not require liquid cooling.

The unit is part of Line 03 and is issued as Version 1. Standardized connector geometry and the slide-in format support installation on a shared backplane with adjacent modules. Closed-loop regulation and onboard diagnostics help the controller respond consistently during demanding motion cycles in multi-axis assemblies. The organized backplane arrangement keeps power and control links centralized inside the drive section. This layout is suitable for systems where several axes operate together under shared machine control.
