HDS03.2-W075N-HT29-01-FW
The HDS03.2-W075N-HT29-01-FW is part of the HDS Drive Controllers series from Bosch Rexroth Indramat. It serves as an axis controller in modular DIAX systems, where commands from a CNC or PLC must be carried out with predictable timing across coordinated motion axes. Within an automation rack, the unit closes the velocity and torque loops that keep brushless motors aligned with programmed motion profiles during acceleration, steady running, and deceleration. This closed-loop control allows the drive system to maintain commanded motion even when load conditions change during normal machine operation.
The drive communicates over the standardized fiber-optic SERCOS interface, allowing high-speed cyclic data exchange and orderly signal routing between multiple axes. It is part of the DIAX04 controller family, which uses the same mechanical format across the platform. Thermal regulation is handled by a built-in air blower that pulls cabinet air through the heat sink, so an external heat exchanger is not required for this module. Current capability reaches 75 A, which supports high transient torque demand from rotary or linear motors under normal operating conditions. The airflow path also helps remove heat from the power section during sustained servo operation.
The product is part of Line 03, which uses the pinout assigned to that design line. As a Version 2 unit, the controller supports later diagnostic functions and parameter blocks. The rack layout uses common cabling across the platform, which keeps axis wiring orderly in multi-axis assemblies. It also uses shared mounting points, so the controller fits the mechanical layout used by related modules. These layout features are part of the platform structure and do not change the controller's role as the power and regulation stage for a servo axis.
