Product Description:

The HDS03.1-W075N-HA38-01-FW drive controller is built by Bosch Rexroth Indramat for inclusion in the HDS Drive Controllers series. Within a DIAX04 multi-axis cabinet it serves as the power and control stage that links a common DC bus to a single servo or spindle motor. Its purpose in industrial automation is to execute precise speed and torque commands, monitor motor feedback, and apply protective shutdowns when electrical or thermal limits are approached.

Operational setpoints are received through an ANALOG command interface, meaning the drive converts a ±10 V reference or a 4–20 mA signal into internal torque and velocity demands. The module belongs to the DIAX04 controller family so it accepts SERCOS fiber-optic feedback rings and uses the same slot mechanics as adjacent axes. Thermal management is handled by a Built-in Internal Air Blower that channels cabinet air through the heat-sink fins; this eliminates external ducting but still keeps semiconductor junctions within limits. The hardware is tagged as line 03, a designation that locks the bus-bar spacing, connector pin-outs, and permissible DC link voltage across the whole rack. Finally, an output capability of 75 A (rms) permits the unit to start and decelerate medium-inertia motors without derating, provided the ambient temperature remains within the values stipulated for internal cooling.

As no alternate firmware or hardware tracks are listed, the "Other Versions" entry is None, which simplifies stock control because every replacement shipped will match the same bill of material. The production revision is 1, so drive firmware packages, parameter listings, and diagnostic tools must reference this index during commissioning. Inside the HDS Drive Controllers series this uniformity allows multi-axis systems to maintain identical response curves and protective limits. Support channels at Bosch Rexroth Indramat rely on that fixed configuration to expedite spare-part logistics and reduce troubleshooting time.
