HDS03.2-W075N-HT05-01-FW
The HDS03.2-W075N-HT05-01-FW is a modular drive controller produced by Bosch Rexroth Indramat in the HDS Drive Controllers series. It occupies a single slot in a rack-based motion system inside the control cabinet, where it works with a central control section and adjacent power components. That arrangement lets one rack support several axes while keeping control and power functions organized in separate modules. In operation, the controller converts digital motion commands into regulated three-phase output for servo or main-spindle motors. Integrated monitoring circuits supervise current, temperature, and communication status during each operating cycle.
The command channel uses the fiber-optic SERCOS interface for deterministic exchange of setpoints, feedback, and diagnostic data with the master controller. Within the DIAX04 platform, the unit is part of Line 03, so its backplane connections follow the signal assignments used for that design line. Thermal management is handled by a built-in air blower that pulls cabinet air through the heat sink and exhausts it upward, which removes the need for external ducting. The power section can supply a continuous output current of 75 A, supporting position, velocity, and torque control in medium-to-high power multi-axis applications. The closed control structure allows the module to respond quickly to load changes while maintaining stable drive behavior.
The unit is Version 2, indicating the second revision for this controller configuration. It is categorized as an HDS Drive Controller, which places it within the modular rack architecture used for coordinated motion systems. Because the controller remains separate from the higher-level motion processor, it can focus on motor current regulation, thermal supervision, and fault response within its assigned axis. Status information from the controller can be used by the machine control to manage interlocks and stop sequences when a fault is detected. This arrangement is suited to industrial machines that require synchronized starts, controlled stops, and stable holding behavior during normal operating cycles.
