Product Description:

The HDS03.2-W075N-HA40-01-FW is a modular drive controller built by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Intended for centralized multi-axis systems, the unit conditions bus power and delivers motion control signals to companion power sections. It translates reference values from higher-level PLCs into precise current and voltage commands that keep attached motors synchronized with process demands. This operating role suits coordinated servo axes in gantry loaders, machining centers, packaging equipment, and other automation lines that depend on repeatable speed and position control.

This controller exchanges setpoints through an analog reference channel, allowing straightforward integration with legacy process controllers that output ±10 V or 0–20 mA signals. Belonging to the DIAX04 controller family, it fits standardized multi-axis racks where power, logic, and feedback connectors share a common backplane. The continuous output capability is 75 A, which is the maximum motor phase current the device can regulate without derating when paired with high-torque synchronous motors. Thermal stability is maintained by a built-in air blower that forces air across the heat sink fins, allowing vertical stacking inside densely populated enclosures without requiring a separate external fan on the controller.

Within the drive stack, the module is assigned to Line 03, which places it in the third design line used for this product platform. It uses Version 2 electronics with updated diagnostic routines. A dedicated command interface terminal strip separates reference wiring from power conductors to reduce noise coupling and keep low-level control signals organized. This arrangement helps maintain cleaner analog signal paths when the unit is installed near higher-current drive components in the same cabinet.
