Product Description:

The HDS03.2-W075N-HS77-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. Designed for installation in DIAX04 multi-axis drive racks, the unit converts drive commands into controlled current for synchronous and asynchronous servo axes in automated machinery. By integrating feedback processing, power electronics, and network communication inside one housing, the controller serves as the actuator interface for coordinated motion, accurate positioning, and stable speed regulation in flexible manufacturing lines. It is commonly used where several axes must respond to controller commands with repeatable timing and consistent current regulation.

It communicates with higher-level PLCs over the SERCOS fiber-optic interface, so setpoint and diagnostic data move across a deterministic cyclic bus. As part of the DIAX04 family, it uses the same basic platform as compatible units in the same rack, which helps mixed-axis systems share a common control structure. The power stage is rated for 75 A continuous output, allowing the controller to support axes that need sustained current during acceleration, running, and load changes. Thermal management is handled by a built-in air blower that circulates cabinet air through the heat sink fins, and the unit is part of Line 03, which marks the third design line.

Version 2 identifies the hardware version used for this model. As an HDS Drive Controller, it uses the standard power and control connections associated with this product type, so it fits the mechanical layout used across the platform. Within the HDS Drive Controllers series, this model occupies a mid-range current class for applications that need more output than the smallest units without moving to the highest-capacity versions. Its form factor is suited to rack-based drive systems where multiple axes are grouped in one cabinet for coordinated machine motion.
