HDS03.1-W075N-HA08-01-FW
The HDS03.1-W075N-HA08-01-FW is a modular drive controller produced by Bosch Rexroth Indramat within the HDS Drive Controllers series. Designed to regulate torque and velocity for servo and induction motors, the unit fits into a common power rail and converts DC bus energy into phase-controlled output for each axis. Because it operates as one axis within a larger drive system, neighboring modules can share the same power structure while each controller manages its own motor channel. In automated machining cells, packaging lines, and material-handling gantries, it supplies closed-loop power so encoder feedback can be used for precise mechanical motion.
Its command channel uses an analog interface, so velocity or torque setpoints are transmitted as differential voltage levels that the controller converts into PWM switching patterns. The current loops are sized for a continuous load of 75 A, enabling the module to drive medium-power axes without external boosters. Thermal management relies on a built-in air blower, which pulls cabinet air through the heat sink to keep semiconductor temperature within limits during sustained operation. This arrangement allows the controller to respond directly to external command references while maintaining stable output current. The circuitry belongs to the DIAX04 controller family. The unit is part of Line 03, indicating the third design line.
This unit is classified as an HDS Drive Controller. It supports standardized module interconnection in multi-axis assemblies, and its mounting and connector arrangement match other controllers in the same platform. The housing format is intended for side-by-side installation on the drive structure, which helps keep axis layouts compact. The product is released as Version 1, which identifies the product generation for this drive type.
