Product Description:

The HDS03.2-W100N-HT84-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It acts as the power stage that converts the shared DC bus of a motion rack into regulated three-phase output for servo or spindle motors, enabling tight velocity and position loops in automated machinery. Typical installations include packaging lines, printing presses, conveyor zones, and machining centers where synchronized closed-loop control is required. This arrangement allows multiple axes to share centralized DC power while each controller regulates its own motor output. The unit mounts in a backplane card cage and draws DC from a common supply section.

Its command layer uses the SERCOS fiber-optic interface, so setpoints, diagnostics, and parameter data are exchanged in real time over a deterministic ring. Thermal management is handled by a built-in internal air blower, which draws ambient air through the heat sink to keep component temperatures controlled without external ducting, provided the cabinet has unobstructed exhaust paths. The power stage delivers a continuous output of 100 A, allowing it to drive medium-to-high torque motors while maintaining the current accuracy needed for servo motion. Real-time optical communication helps coordinated axes respond with consistent timing during demanding machine cycles. The unit is part of Line 03, which uses the mechanical size, connector positions, and mounting rail pattern assigned to that design line.

As part of the DIAX04 controller family, the module is listed as Version 2. Within project documents, it is identified as an HDS Drive Controller. It is intended for use in a multi-axis digital drive system, where coordinated axes share cabinet infrastructure and a common control architecture. The version marking indicates the product revision used for this controller type, and the concise naming keeps device references consistent across drawings and cabinet layouts.
