Product Description:

The HDS03.1-W100N-HT20-01-FW is a drive controller built by Bosch Rexroth Indramat and positioned within the HDS Drive Controllers series. In a DIAX04 automation rack, this module acts as the axis controller, translating motion commands into regulated current and velocity references for connected servo or induction motors. By providing closed-loop control and coordinated braking functions, the unit supports precise positioning, speed regulation, and torque control in packaging machines, material-handling systems, and machine tools. The result is stable motion on axes that must accelerate, decelerate, and hold commanded speed accurately through repeated operating cycles. It mounts on a standardized backplane where it interfaces with dedicated power supplies and communication boards as part of a scalable multi-axis platform.

The controller exchanges setpoints, actual values, and status information over SERCOS, which provides time-deterministic communication between drives and the master PLC through a fiber-optic network. Because command and feedback data are exchanged cyclically, the controller can react quickly to speed corrections and load changes during operation. Electrical and mechanical compatibility with the DIAX04 family means the module can share a common DC bus and follow identical addressing conventions across axes. Thermal management is maintained by a built-in air blower, which pulls control-cabinet air across the heat sink to keep semiconductor junction temperatures within safe limits when the converter is delivering its continuous 100 A output. The board set includes resolver feedback conditioning, overspeed monitoring, and programmable fault reaction modes that allow shutdown behavior to be tailored to the application.

The unit is part of Line 03 and uses the connector layout associated with that design line. This hardware is released as Version 1, which identifies the initial production revision. Uniform parameter numbering keeps settings organized across multi-axis installations. The consistent slot format also helps the module fit cleanly with companion units in the same rack, which supports orderly cabinet layout when several axes are installed together.
