Product Description:

The HDS03.2-W100N-HT74-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed within multi-axis drive racks, the module operates as the power and control stage between a central motion processor and servo motors. Its job in industrial automation is to convert high-level movement commands into regulated motor currents while providing real-time feedback, enabling coordinated positioning, velocity, and torque control on packaging lines, machining centers, and material-handling cells. This closed-loop operation helps the controller maintain stable axis response during acceleration, deceleration, and changing load conditions.

The controller exchanges data with higher-level control systems over the SERCOS fiber-optic bus, which supplies deterministic, cyclic setpoint and diagnostic frames needed for synchronized multi-axis motion. That communication link helps keep command updates and status information aligned across multiple axes in the same system. The power section is rated for 100 A, permitting it to drive large continuous-current servo motors without external boosters. Thermal energy from the switching devices is removed by an internal air blower, so the module can be mounted in a sealed cabinet without auxiliary ducting. Within the DIAX04 family, this model follows a standardized pinout and parameter structure, allowing consistent setup across different current ratings.

The unit is part of Line 03 and Version 2. The product classification is HDS Drive Controller, which distinguishes it from HMS supply units and HVE power supplies used in the same rack. Its modular design lets the optical fiber, motor leads, and encoder cables plug directly into the front panel, placing the command communication interface and power stage on the same board for short signal paths. Front-facing connections also help keep cable routing organized in dense control cabinets where several drive modules are installed side by side.
