Product Description:

The HDS03.2-W100N-HT71-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Classified as a multifunction axis module, it coordinates power stages and feedback loops for servo and spindle drives in multi-axis automation racks. Within integrated machining cells or material-handling stations, it closes torque, speed, and position loops so connected motors follow programmed trajectories under PLC supervision. The module mounts on a shared cold plate and draws DC-bus energy from an HVE supply, which supports compact cabinet layouts in industrial automation. This arrangement lets one cabinet support several coordinated axes while keeping the control structure centralized for complex machine motion.

Communication relies on the optical SERCOS ring, and this deterministic bus moves setpoints and diagnostic data between the controller and the master within a 1 ms cycle. The power section carries a continuous rating of 100 A, allowing the unit to drive large synchronous or induction motors without derating. Heat produced by switching losses is removed by an internal air blower that circulates cabinet air across the heat sink, so external ducting is unnecessary. The fiber pair entering the front edge serves as the primary command interface, which eliminates analog wiring and improves noise immunity. That setup supports repeatable data exchange for coordinated motion, interpolation, and status monitoring during continuous machine operation.

The controller is intended for the DIAX04 motion platform, where it exchanges control data with compatible system modules. The unit is part of Line 03, so it shares mechanical dimensions and connector positions with other third-generation HDS modules. It is released as Version 2, which provides updated diagnostics and expanded parameter memory compared with the original release. Updated diagnostics help the system report operating states and faults more clearly during startup and routine operation.
