Product Description:

The HDS03.2-W075N-HS76-01-FW drive controller is an axis module in the HDS Drive Controllers series. Produced by Bosch Rexroth Indramat, the unit functions as a power stage and motion processor, translating digital setpoints into regulated three-phase output for automation axes. In a multi-axis rack, it supports rapid positioning, coordinated motion, and diagnostic feedback for servo motor systems connected to industrial CNC or PLC controls. Its cabinet-mounted format suits machine layouts that require centralized drive electronics while keeping motor command processing and power conversion in the same module.

Communication takes place over SERCOS, a fiber-optic interface that transfers setpoint, status, and parameter data in deterministic time slots so multiple axes can remain synchronized with the central motion controller. The power section is rated for 75 A, allowing the module to energize medium-frame AC servo motors without current derating across the full torque range. Thermal management relies on a built-in air blower, which channels cabinet air through the heat sink to stabilize semiconductor temperatures during sustained load. The module belongs to the DIAX04 family, so it follows the standardized rack format used by related control and bus components on that platform.

Within the product line, the controller is part of Line 03. This places the unit in a 300 V DC bus group that shares common supply units with compatible modules in the same rack. The arrangement supports coordinated multi-axis operation and keeps the power architecture consistent across connected axes. Because the controller combines motion processing with the output stage, it can serve as a compact drive element in cabinet installations where reliable servo control, orderly rack integration, and clear electrical grouping are required.
