Product Description:

The HDS03.2-W075N-HA03-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Integrated into automation cabinets, it supplies regulated power to synchronous or asynchronous axes and executes motion commands from higher-level PLCs. In automated machining centers and material-handling lines, the unit translates reference values into precise motor torque and speed. This supports coordinated axis motion during positioning, feed control, and other synchronized machine movements. The controller therefore fits applications that need repeatable acceleration, deceleration, and speed regulation across several machine functions.

This controller exchanges setpoint and feedback data over an analog command interface, allowing straightforward wiring to legacy CNC or PLC hardware that outputs ±10 V references. Its continuous output capability is rated at 75 A, so motors and drive sections operating at that nominal current can be supplied without derating. Thermal management is handled by a built-in air blower, which moves air across heat sink fins and keeps semiconductor junction temperatures within safe margins. The unit belongs to the DIAX04 family, and the product is part of Line 03. That platform pairing keeps the electrical layout and connector placement consistent with other modules used in the same control architecture.

The unit is Version 2 and remains pin-compatible with prior backplanes in the HDS Drive Controllers series. Diagnostic messages and parameter maps remain consistent across compatible racks, which helps keep multi-axis behavior uniform within the same platform. This controller is intended for cabinet-based assemblies where several axes must respond to command changes without delay. Its modular format also suits systems that separate the power stage, control functions, and machine-level logic across dedicated components.
