Product Description:

The HDS03.2-W100N-HS03-02-FW drive controller is manufactured by Bosch Rexroth Indramat. It operates as a single-axis module, converting shared DC-bus power into regulated three-phase output for servo motors in assembly, packaging, and material-handling machinery. This arrangement lets the drive deliver controlled current for accurate torque and speed response during indexing, positioning, and other synchronized machine movements. Because it uses a shared DC-bus arrangement, the module works with a centralized power system rather than a standalone mains input at each axis. The housing format is intended for installation in a modular rack, and the unit is part of the HDS Drive Controllers series.

This unit receives motion commands through the optical SERCOS interface, so cyclic setpoints and diagnostic data travel on a fiber-optic loop. The optical link carries command values, response data, and diagnostics over the same communication path. Its power stage is designed for a continuous output of 100 A, making it suitable for high-torque motors during sustained duty cycles. Heat generated by switching devices is removed by a built-in air blower, which draws ambient air across the heat sink without external ducting. The module is used in the DIAX04 platform, where it works with shared supplies and I/O connections in a rack. Optical communication also supports stable data transfer in electrically noisy industrial cabinets and keeps command exchange synchronized across connected axes.

In a multi-axis cabinet, the hardware designation of line 03 matches the slot mechanics and connector pinouts used by the platform. The device is marked as version 2, which indicates the product revision for this controller type. The status word on the bus identifies the controller family alongside diagnostic flags, allowing the control system to monitor current limits, cooling airflow, and the condition of the optical ring. The reported data can be used by the PLC to react to faults before motion quality is affected. This operating data helps the higher-level controller verify normal drive behavior during coordinated motion.
