Product Description:

The HDS03.2-W075N-HS55-01-FW belongs to the HDS Drive Controllers series produced by Bosch Rexroth Indramat. As a modular drive controller, it is installed in DIAX04 multi-axis systems, where it interfaces with higher-level motion controls and supplies regulated current to servo motors. Within an automation cell, the unit closes the loop between numeric command sequences and the mechanical load, allowing coordinated velocity, torque, and position control on a single machine axis. That arrangement allows the axis to follow commanded speed changes and positioning moves as part of coordinated machine motion. It occupies one slot on the common DC bus and relies on a matched supply module for incoming power.

This controller exchanges motion data over the SERCOS fiber-optic ring, so real-time axis status travels on a deterministic serial bus. During operation, the power section can deliver a continuous output of 75 A, matching medium-to-high torque servo motors used in packaging or material-handling machines. The unit is part of the DIAX04 family, so it shares the rack backplane and supply structure used by other modules in the system. Thermal control is handled by a built-in air blower that directs cabinet air across the heat sink without external ducting. The drive is part of Line 03 in the series, which identifies the third design line.

The drive controller is Version 2. This version supports later diagnostic functions in compatible systems while keeping the unit aligned with the established platform layout. Because the controller works from the shared bus structure rather than a stand-alone mains input, it suits rack-based servo assemblies that divide power and control functions among separate modules. Its role is to regulate motor current for one assigned axis while communicating continuously with the higher-level control. This arrangement is intended for cabinet-mounted installations where multiple axes operate from the same drive stack.
