Product Description:

The HDS03.2-W075N-HS08-01-FW is a drive controller produced by Bosch Rexroth and assigned to the HDS Drive Controllers series. It occupies a single-axis slot in a modular rack and channels DC-bus energy to a connected servo motor. By translating high-level motion commands into timed current pulses, the unit coordinates position, speed, and torque across conveyors, gantries, and machining centers in industrial automation. This arrangement allows one controller to serve as the power stage for an individual axis while still operating as part of a larger multi-axis system. Because the rack architecture separates motion duties by axis, the controller can be integrated into machines that require coordinated yet independently regulated movement.

This controller communicates over the SERCOS fiber-optic ring, so cyclic setpoints, actual values, and diagnostics move in real time with deterministic latency. That communication path supports synchronized updates between the control system and the drive without relying on conventional parallel wiring. During operation, it can supply up to 75 A of continuous output, so the connected power path must be sized for sustained current rather than brief peaks alone. Thermal regulation is handled by a built-in air blower that draws enclosure air across the heat sink and removes the need for external ducting. The unit belongs to the DIAX04 family, which keeps it aligned with other rack-based axes that use the same control platform and communication method.

Within the type code, it is identified as an HDS Drive Controller and assigned to power line 03, placing it in the third current tier of the series. The product is Version 2, which indicates the second revision level for this unit. Those identifiers help distinguish it from earlier or lower-current members of the same product line. It also carries Bosch Rexroth Indramat branding used across the HDS platform. The controller delivers timed current pulses to the motor so commanded motion can be tracked with stable speed response, controlled torque output, and coordinated positioning in modular servo racks.
