Product Description:

The HDS03.2-W100N-HS25-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series for multi-axis motion systems. It serves between the plant power supply and individual servo motors by converting DC link energy into regulated three-phase output for controlled motion. Installed in a control cabinet, the unit supports packaging, printing, and material-handling machinery that requires fast torque response and stable axis control. This arrangement lets the controller act as the power stage for servo axes while the higher-level control system manages the motion profile. Its modular format also suits cabinet-based drive assemblies where several axes operate from a shared power structure.

A digital command path based on the SERCOS interface handles position, velocity, and diagnostic telegrams across a fiber-optic loop. The fiber loop supports synchronized data exchange between the motion control and the axis module during operation. The power electronics are rated for a continuous output of 100 A, giving the axis enough headroom for rapid acceleration without thermal derating. To remove switching losses, a built-in air blower moves enclosure air across the heat sink fins instead of requiring external ducting. As part of the DIAX04 family, the controller shares compatible slot width and voltage bus arrangement with companion axes. The unit is Version 2.

The product is part of Line 03, placing it in the same mechanical frame size as related modules and allowing common busbar layouts. Steady airflow through the integral fan is maintained when the surrounding cabinet temperature stays within the permitted operating range. That cooling path supports continuous heat removal from the power section during normal operation. The fixed housing format also helps the module fit cleanly into multi-axis racks that use the same platform geometry.
