HDS03.2-W075N-HS26-01-FW
The HDS03.2-W075N-HS26-01-FW is a digital drive controller built by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. Within a modular drive rack, it supplies regulated power and closed-loop axis control to synchronous and asynchronous servo motors used in production machinery, material-handling lines, and packaging equipment. It converts setpoint data from a higher-level motion processor into precisely timed current pulses so the connected axis can follow commanded speed and torque profiles. Because the control loop is handled inside the unit, the machine can maintain smooth acceleration and deceleration during repeated positioning cycles.
The controller exchanges real-time setpoints and status bits through the SERCOS fiber-optic ring, which supports deterministic cycle timing in multi-axis motion systems. This communication method keeps command updates synchronized across linked axes, which is important in transfer systems, indexing equipment, and coordinated handling tasks. Its output stage sustains a continuous current of 75 A, allowing it to drive high-torque motors without an external booster. Thermal energy from the power semiconductors is removed by a built-in air blower, so cabinet airflow is easier to manage. The unit is part of the DIAX04 platform and uses matching backplane connections for installation in compatible drive racks.
Within the series coding, the line designation 03 corresponds to the mechanical format used with standard supply modules and shared DC bus bars. The unit is Version 2 and includes updated diagnostics with expanded parameter ranges. Its command communication interface supports approved telegram structures for stable cyclic timing during operation. The controller fits standard rack layouts in which power conversion, feedback handling, and motion regulation are separated into coordinated modules.
