HDS03.2-W100N-HT11-01-FW
The HDS03.2-W100N-HT11-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Engineered for DIAX multi-axis systems, the unit serves as the axis control stage that translates motion commands into regulated current for servo power sections. Within automated assembly stations and processing cells, it coordinates speed, torque, and position loops so mechanical loads follow programmed trajectories with repeatable precision. Because it manages loop behavior at the axis level, the controller helps the connected drive section respond smoothly to changing loads, direction changes, and programmed positioning sequences.
Field communication is provided through the SERCOS optical ring, a deterministic protocol that transports real-time setpoints and status data. The dedicated command interface on the front panel handles ring initialization, diagnostics, and cyclic telegrams without requiring an external gateway. For power delivery, the controller can sustain a phase output of 100 A, which suits medium-to-large servo axes that need rapid acceleration and stable current control during demanding motion profiles. Thermal energy is removed by a built-in air blower that circulates cabinet air across the heat sink for continuous operation. This cooling method supports steady performance in enclosed installations where direct external ducting is not used.
The module is part of the DIAX04 architecture and uses hardware Version 2. The product is assigned to Line 03, which identifies the third design line in this platform. Version 2 supports faster processing and expanded parameter memory for interpolation tasks and routine diagnostics during machine operation. In a cabinet, the controller works within a coordinated multi-axis platform so communication timing, current regulation, and axis response remain closely synchronized across neighboring drive sections.
