Product Description:

The HDS03.1-W075N-HS63-01-FW drive module is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Serving as a power section inside modular multi-axis racks, it converts the shared DC bus voltage into controlled three-phase outputs for servo motors. By doing so it establishes closed-loop regulation of torque, speed, and position in machining centres, handling systems, and automated assembly lines.

Process data enter the module over the SERCOS fibre-optic loop, the designated command communication interface that links multiple axes to a single CNC or PLC. During operation the controller can deliver a continuous phase current of 75 A, a figure that defines the thermal sizing of connected motors and conductors. Excess heat generated at this load is discharged by a built-in internal air blower, allowing the unit to remain in an IP20 control cabinet without external ducts. The power electronics belong to the DIAX04 automation system, so parameter sets and diagnostics are exchanged with neighbouring drive cards through the back-plane, completing synchronous multi-axis motion.

This device is identified in order tracking as an HDS Drive Controller, and within the hardware matrix it occupies Line 03, meaning it follows the third mechanical and electrical layout revision. The production release carries Version 1, so all firmware, parameter blocks, and accessories must match that revision; the catalogue lists no other versions for this specific ordering code. From a controller family standpoint the module fulfils the axis-specific amplification role while the separate supply unit manages the shared DC bus, ensuring predictable current delivery during acceleration and regenerative braking.
