Product Description:

The HDS03.2-W075N-HS98-01-FW is a drive controller manufactured by Bosch Rexroth Indramat within the HDS Drive Controllers series. The unit converts setpoint data from a master control system into regulated current for an attached servo or induction motor, allowing precise torque and velocity regulation in multi-axis industrial machinery. It serves as an axis module in a common DC bus rack for coordinated motion in packaging, printing, and material-handling lines. In this role, the controller functions as the power stage for one axis while operating within a shared rack-based drive system.

The controller exchanges cyclic setpoints and status words over the SERCOS fiber-optic interface, so parameter data and real-time position values move deterministically between the drive and the system PLC. That communication path supports synchronized response across multiple axes without separate analog command wiring. A continuous output capacity of 75 A allows the module to supply high-torque motors without external booster hardware. Thermal limits are managed by a built-in air blower, which pulls cabinet air through the heatsink and keeps semiconductor junction temperatures within a safe range. Because the unit belongs to the DIAX04 controller family, it shares a common backplane and power supply arrangement with other compatible axes.

Within the type code, the module is identified as Version 2. This version includes second-generation diagnostic functions and updated parameter memory for the control electronics. The designation Line 03 places the controller in the medium-current range of the series, between lower-current Line 02 units and higher-current Line 04 variants. This placement suits medium-duty axes that need substantial current capacity without moving to the largest power class in the line.
