HDS03.2-W075N-HA14-01-FW
The HDS03.2-W075N-HA14-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It serves as a closed-loop amplifier that converts velocity or torque setpoints from a CNC or PLC into precisely modulated three-phase outputs for servo and spindle motors. By supervising motor feedback and executing current, velocity, and position loops in real time, the unit maintains consistent motion profiles across demanding duty cycles. The controller is intended for coordinated motion systems where multiple axes must follow commanded paths with repeatable timing.
Command data reach the controller through an analog interface, so scalable voltage or current references dictate the demanded motor behavior without requiring a digital fieldbus command channel. The integrated power electronics can supply a continuous output of 75 A, allowing the module to drive sizable axes without thermal derating. A built-in air blower channels cooling air across the heat sink, removing losses produced at high current while preserving enclosure space. As part of the DIAX04 family, the controller shares a common backplane and DC bus with companion modules for synchronized operation and simplified power distribution. The controller is Version 2, indicating an updated release with revised diagnostics and parameter handling.
Within the rack, the module occupies Line 03, so its address mapping, monitoring LEDs, and test points correspond to that slot. The functional designation HDS Drive Controller means current, speed, and fault management routines run locally without external computing resources. It mates with matching power supplies, feedback cards, and bus cables to build coordinated axis packages. Local control processing lets the module respond directly to motor feedback during acceleration, speed regulation, and fault monitoring, which is useful in servo and spindle applications that require stable closed-loop behavior.
