Product Description:

The HDS03.1-W075N-HA36-01-FW is a modular drive control unit produced by Bosch Rexroth Indramat for incorporation into the HDS Drive Controllers series. As a drive controller, it coordinates the power stage of an electric servo axis and relays motion commands from higher-level automation equipment to the connected motor. Within an industrial installation, it forms part of a multi-axis DIAX04 rack, translating reference signals into regulated current so that machinery such as gantries, packaging lines, or material-handling stations maintain precise speed and torque profiles.

The controller accepts reference data through a ANALOG command interface, allowing ±10 V velocity or torque setpoints to be wired directly from PLC analog output cards. Its continuous output capability is specified at 75 A, indicating the maximum line-to-line current the inverter stage can supply to a synchronous motor without derating. Thermal energy created by switching losses is removed with a Built-in Internal Air Blower; the integrated fan pulls cabinet air through the heatsink channel, eliminating the need for ducted external cooling. Because the unit belongs to the DIAX04 controller family, it plugs into a common backplane that distributes DC bus power and shared logic signals across multiple axes. The designation Line 03 identifies its mechanical layout and firmware slot arrangement, ensuring compatibility with ancillary power supplies and feedback modules released for the third design line.

This hardware is shipped in Version 1 form, making it the initial revision for its hardware lineage and therefore the reference point for subsequent firmware updates. Classified explicitly as an HDS Drive Controller, it dictates closed-loop behaviour while upstream motion processors handle path calculation. The naming convention ties it to Bosch Rexroth Indramat engineering standards, and its placement in the HDS Drive Controllers series allows uniform parameter handling across axes in the same rack.
