Product Description:

The HDS03.1-W075N-HA22-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for cabinet-mounted motion systems, the unit interfaces with a central motion manager and supervises the power stages that energize one or more synchronous servo axes. By translating velocity and torque references into precise current and voltage patterns, it helps coordinate automated tooling, packaging, and material-handling lines while protecting connected motors and supply buses.

The command path relies on a ANALOG signal structure, so ±10 V velocity or torque references can be delivered from a PLC or motion card through the designated Command Communication Interface. Within the Rexroth control hierarchy the unit is assigned to the DIAX04 family, allowing parameter consistency and shared diagnostics across companion drives. Electrical loading is defined by a Rated Current ceiling of 75 A, meaning the controller’s output stage and protective circuits are dimensioned for motor groups drawing that continuous line current. Thermal stability is maintained by a Built-in internal air blower that channels cabinet air across the heatsink and expels it through a rear duct, eliminating the need for external fans.

Model classification uses Line code 03 to denote hardware layout and connector placement that match other third-line modules in the series. Firmware and parameter sets are installed under Version identifier 1, ensuring the control logic aligns with the power electronics and diagnostic routines of this release. The catalog lists None for alternate hardware variants, so performance, cooling, and interface options remain constant across all units carrying the same ordering code, simplifying spare-part logistics in multi-axis DIAX assemblies.
