Product Description:

The HDS03.2-W075N-HA38-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a multi-axis rack, it regulates torque and speed on one servo axis by converting upper-level motion commands into controlled motor current. The module is intended for machine tools, packaging stations, and material-handling systems where stable axis response is required. It also reports fault states back to the PLC, allowing the control system to react when the axis is overloaded or stopped by a protective function. Because it is a modular unit, it works with the rack power section instead of serving as a standalone drive.

The controller delivers a continuous output of 75 A, allowing it to run medium-power servomotors without requiring separate cooling equipment. Command setpoints arrive through an analog interface, so the PLC sends the velocity reference as an analog voltage signal and handles the related scaling. Internal heat is removed by a built-in air blower, which moves cabinet air across the heat sinks and helps keep component temperatures stable during sustained operation. This cooling method supports repeated duty cycles where the axis must accelerate, decelerate, and hold speed with consistent electrical performance.

The product belongs to Line 03, so it fits the rack depth used by comparable axes in a DIAX04 system. The unit is Version 2, which uses updated gate drivers to reduce switching loss and limit heat rise during high-duty operation. Status information is shown through diagnostic LEDs, allowing operating and fault conditions to be checked directly at the module face. The rack layout also keeps neighboring axis modules on the same depth line, which helps maintain consistent panel spacing. This arrangement keeps the controller aligned with the module layout and operating structure used across the rack.
