HDS03.2-W100N-HT02-01-FW
The HDS03.2-W100N-HT02-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. It serves as a digital axis module in the HDS Drive Controllers series and works with higher-level motion control hardware to regulate the power stage for AC servomotors. In multi-axis machinery, the unit converts motion commands into controlled motor current so synchronized moves, speed regulation, and repeatable positioning can be maintained across automation cells and machining centers. Its modular format also suits rack-based drive systems where several coordinated axes operate from the same power platform.
This unit exchanges setpoints and feedback over the SERCOS fiber-optic bus, allowing deterministic communication with the motion controller and stable timing between linked axes. A continuous output of 100 A supports sustained motor demand during heavy-load operation and gives the module the capacity needed for large servo applications. Thermal stability is maintained by a built-in air blower that moves cabinet air through the heat sink and removes heat without external ducting. The product is part of Line 03, and its compatibility with the DIAX04 family allows it to share a common DC bus with related drive modules in the same machine assembly.
The controller is Version 2. It is supplied with no resolver evaluation board and no encoder evaluation board, so any required feedback processing must be handled by the matching system arrangement rather than inside this module. That layout fits installations where feedback functions are assigned elsewhere in the drive rack, while the axis module remains focused on power control and communication tasks. This separation keeps the operating role of the module clear within a coordinated drive system and avoids unnecessary overlap with dedicated feedback hardware.
