Product Description:

The HDS03.1-W100N-HT13-01-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied within the HDS Drive Controllers series. As an axis module in modular motion systems, it governs current, velocity, and position loops for servo motors. In this role, the unit acts as the control link between the higher-level motion system and the motor power stage. It is intended for coordinated automation tasks where several axes must respond accurately to changing commands. Typical applications include automated production lines, machine tools, and material-handling cells.

Communication with supervisory PLCs occurs over the industrial fiber-optic SERCOS interface, allowing synchronized cycle times and deterministic data exchange. This communication method supports coordinated timing across linked motion axes in the same system. The power section is rated for a continuous output of 100 A, so inverter stages and wiring must be sized to carry that current without derating. Thermal management is provided by a built-in air blower, which circulates cabinet air across the heat sinks and removes the need for external ducting. This HDS unit belongs to the DIAX04 controller family, so it follows that platform's established parameter structure and overall mechanical outline. The product is part of Line 03 in the series.

The drive controller is Version 1. The device uses matching mounting dimensions and shared bus bar positions that support multi-axis rack assembly alongside supply and auxiliary modules. Within a complete motion chain, the HDS Drive Controller processes motion commands and modulates inverter transistors according to feedback from the attached motor encoder. Encoder feedback is used continuously so current, speed, and position corrections can be applied during operation. This arrangement allows the connected motor to follow commanded speed changes, torque demands, and position targets with stable closed-loop response.
