HDS03.2-W075N-HT01-01-FW
The HDS03.2-W075N-HT01-01-FW is an HDS Drive Controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. It serves as a programmable drive control module for torque and speed regulation on AC servo axes in multi-axis machining centers, packaging cells, and material-handling systems. Digital setpoints from higher-level motion hardware enter the unit and are converted into regulated motor currents, allowing precise positioning and coordinated velocity control in automated production lines. It can function as the control stage for axes that must accelerate, decelerate, and hold commanded speed with consistent regulation during continuous machine cycles.
Its electrical capability is based on a continuous output of 75 A, which is the maximum phase current the unit can supply without exceeding thermal limits. The associated rated current helps determine conductor sizing and overcurrent protection for the connected axis. Command exchange with a CNC or PLC master occurs through SERCOS, a deterministic fiber-optic ring for high-speed transfer of setpoints, feedback, and diagnostic data. Thermal management relies on a built-in internal air blower, which forces cabinet air across the heat sinks and removes the need for separate external fans. A configurable communication interface setting allows bus update rates to be aligned with application dynamics so loop performance remains stable.
This module belongs to the DIAX04 controller family, so its mechanical footprint matches companion devices in that rack system. It is part of Line 03, indicating the third design line used for this controller. The unit is Version 2, which identifies its revision level within the product line. Its family assignment also indicates compatibility with the general rack arrangement used by related modules in the same platform.
