HDS03.1-W100N-HS72-02-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W100N-HS72-02-FW is a digital drive controller built by Bosch Rexroth Indramat and placed in the HDS Drive Controllers series. It regulates torque, speed, and position for servo axes in automated machinery, enabling precise motion profiles while maintaining coordinated multi-axis operation within industrial production cells. It occupies a single slot within a DIAX04 rack and supplies controlled power to motors through pulse-width-modulated outputs. By integrating command processing, power electronics, and cooling hardware in one housing, the unit supports compact cabinet layouts commonly found in packaging, machining, and material-handling lines.

The drive exchanges set-point and feedback data through the SERCOS fiber-optic bus, allowing cyclical communication with PLC or motion controllers at microsecond intervals. Belonging to the DIAX04 family, it can be combined side-by-side with other HDS or HMS modules that share the same DC link. Thermal management is handled by a built-in internal air blower, so the enclosure does not rely on cabinet airflow and can maintain power semiconductors within allowable junction temperatures. The power stage is sized for a continuous 100 A output rating, giving adequate headroom for rapid acceleration of medium-to-large servo motors. Hardware identifier 03 marks the line variant that matches this current class and mechanical footprint.

Version code 1 defines the baseline hardware release for this model, and the list of additional variants is None, simplifying spare-part logistics. Application-specific firmware is stored on the front plug-in card, enabling parameter updates without altering the power section. The controller can tie into the distributed emergency-stop circuit; when the circuit triggers, the shutdown chain interrupts gate signals so the power stage collapses quickly, limiting residual energy on the shared DC bus.
