Product Description:

The HDS03.1-W075N-HS36-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in multi-axis cabinets, the unit converts digital motion commands into regulated output currents, enabling precise acceleration, speed, and torque control of servo or induction motors in automated tooling and material-handling equipment.

At the communication layer, the controller links to the supervisory PLC through the SERCOS fiber-optic ring, allowing cyclic set-point transfer and real-time status feedback. Power delivery is governed by a continuous output rating of 75 A, so the connected motor windings receive sufficient current for high-torque moves without overloading internal semiconductors. Thermal energy generated by this load is removed by a built-in internal air blower, an integrated fan that channels cabinet air across the heat sink instead of relying on external cooling ducts. Functionally the module is classified as an HDS Drive Controller, meaning its firmware contains application-specific current, velocity, and position loops that are preconfigured for the HDS architecture.

Within the broader DIAX04 automation platform, this unit occupies Line 03, matching it electrically and physically to corresponding power supplies and feedback modules on the common backplane. It carries Version 1 firmware and hardware identifiers, and there are no other versions of this exact type code, simplifying spare-part selection for maintenance personnel. The fixed Command Communication Interface and the previously cited cooling strategy are not field-convertible, so system designers must allocate cabinet airflow and network bandwidth during the initial build. These attributes position the module as a stable axis amplifier for installations that standardize on reference encoders and synchronized SERCOS loops.
