HDS03.1-W100N-HA34-01-FW
The HDS03.1-W100N-HA34-01-FW is a single-axis drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Positioned between a machine control system and an electric servo motor, it converts external motion commands into regulated current and speed control for precise axis movement. This arrangement supports accurate positioning and stable continuous-duty operation in machine tools, packaging equipment, and automated handling cells. It is suited to applications where the drive must respond quickly to changing load demand while maintaining predictable motion.
The power stage is rated for a continuous output of 100 A, allowing the unit to drive medium-to-large servomotors without reaching thermal limits during normal operation. Motion references arrive through an analog command interface, so the controller can interpret voltage-based commands from legacy or stand-alone control equipment without requiring a digital fieldbus. This makes it suitable for systems that still rely on direct analog command signals for axis control. Heat from the IGBT section is removed by a built-in internal air blower, which circulates cabinet air across the heat sink. The unit is part of the DIAX04 family, giving it a consistent connector layout for use with compatible system modules.
The designation Line 03 identifies the third design line in this product family, and the unit is marked as Version 1. These identifiers indicate the product generation used for this controller and help distinguish it from other line revisions within the same platform. Its control architecture is intended for applications that rely on steady current regulation and repeatable speed response rather than network-based command handling. Because the drive serves as the power stage between the control source and the motor, it supports axis operation where smooth response and stable loop control are required throughout repeated production cycles.
