Product Description:

Bosch Rexroth Indramat manufactures the HDS03.1-W075N-HT11-01-FW, a drive controller within the HDS Drive Controllers series. The unit operates as the axis module in DIAX04 motion systems, receiving set-point data from a central controller and modulating the current supplied to synchronous or induction servo motors. By converting the shared DC-bus voltage into precisely timed three-phase output, it maintains position, speed, and torque accuracy required for machining centres, packaging lines, and automated assembly cells. It accepts set-point data over high-speed fibre and modulates the motor phases in real time.

The controller supplies a continuous output of 75 A, the maximum phase current it can deliver without thermal derating. Motion commands arrive over the fibre-optic SERCOS interface, enabling deterministic cyclic data exchange and parameter access. Cooling is handled by a Built-in Internal Air Blower that draws cabinet air across the heatsink and keeps junction temperatures within limit. Service staff can use Bosch Rexroth Indramat diagnostic tools to view current, temperature, and network status without removing the unit.

This hardware is identified as design Line 03 and release Version 1, so firmware and parameter files must match these codes during replacement. Within the DIAX04 family it is tagged as an HDS Drive Controller, allowing it to share mounting rails, DC-bus links, and feedback connectors with adjacent axes. The ordering list specifies no other versions, simplifying spare-part logistics because a single catalog number covers all installations. This helps reduce commissioning time on multi-axis machinery.
