HDS03.1-W075N-HS65-01-FW
The HDS03.1-W075N-HS65-01-FW drive controller is produced by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. Designed for the DIAX04 automation platform, the module serves as a power and control stage for synchronous or induction motors in multi-axis machining centers, printing lines, and handling systems. It accepts commands from a fiber-optic master and modulates motor phase current accordingly. This arrangement allows coordinated torque and speed control across several connected axes without separate analog command wiring. In this role, the controller regulates commanded motor behavior while supporting the fast response expected in automated production equipment.
All axis commands pass through the SERCOS optical interface. This deterministic bus updates position words and parameter data every 250 µs, so the drive can synchronize with neighboring axes during fast motion sequences. Optical communication also helps prevent electrical noise from affecting low-level command signals inside complex cabinets. The power section sustains a continuous phase output of 75 A, which is the maximum RMS current the module can deliver under rated cooling before thermal limiting begins. Heat is removed by a built-in internal air blower that draws cabinet air across the heat sink, so an external fan tray is not required.
The unit belongs to Line 03, which indicates the third mechanical size in the series. Its control electronics use the same parameter structures and diagnostic telegrams as other units on that platform. This model is released as Version 1, which corresponds to the first hardware revision for the circuit layout and component set. Signal processing, current regulation, and diagnostic reporting are handled within the same module, which supports predictable behavior during coordinated axis movement. The controller is intended for applications where several drives exchange cyclic data and respond to common motion commands at the same time.
