HDS03.1-W075N-HT12-01-FW
The HDS03.1-W075N-HT12-01-FW is an axis control module produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Mounted in a multi-axis cabinet, it receives velocity or position setpoints from a higher-level PLC and converts them into phase-correct gate signals for connected power sections. The unit closes the current loop for each motor to maintain precise torque regulation across coordinated axes. By regulating motor current directly, it supports fast torque response and stable axis coordination during contouring, indexing, and other continuous-duty motion tasks used in machine tools, packaging cells, and material-handling gantries.
The command layer is linked through the SERCOS fiber-optic interface, so deterministic cycles and real-time parameter exchange are maintained when several axes share the bus. This allows command updates and status feedback to remain aligned across the network during synchronized motion. A continuous output capability of 75 A allows the controller to energize medium-power servo modules, while short-term overload capacity supports brief demand peaks during acceleration or deceleration. Thermal management relies on a built-in internal air blower that circulates cabinet air across heat-sink fins and removes switching losses without external ducting. Integration into the DIAX04 family keeps the configuration structure and I/O mapping consistent with related HDS and HMS units.
The unit is part of Line 03 and is marked as Version 1. It is classified as an HDS Drive Controller, which identifies its role in a servo drive system and distinguishes it within the product line. These identifiers indicate the product generation used for this controller and separate it from other lines or revisions with different electrical behavior. Its role is limited to axis control, so the connected power section provides the high-power output stage while the module manages regulation and communication for coordinated multi-axis applications.
