Product Description:
The HDS03.2-W075N is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed in a cabinet with matching power supplies, it converts the shared DC bus into regulated three-phase output for connected motors while processing encoder feedback for closed-loop control. In automated cells, it acts as the axis amplifier, executing velocity and torque commands so that assembly, cutting, or packaging equipment maintains repeatable motion profiles.
The controller delivers a continuous output of 40 A at a 4 kHz switching frequency, providing stable current to servo windings during sustained operation. A maximum output frequency of 1000 Hz allows the unit to address high-speed spindle or linear motors without saturation. Output voltage can reach 500 V, matching DC bus levels typical of 400 VAC supply systems. Internal logic and I/O circuits run from a nominal control voltage of 26 VDC, and protection against particulate ingress is classified as IP10. Thermal management is handled by a built-in air blower, so no external fan panel is required. Control electronics draw 25 W, and the encoder supply can source 150 mA for position sensors without overloading the low-voltage section.
During acceleration, the unit can source a peak current of 75 A, enabling short bursts of high torque. Continuous switching losses translate into 220 W of heat that the blower ejects from the 100 mm × 498 mm × 308 mm housing. The assembly weighs 11 kg, which supports stable panel mounting and helps damp vibration. Installation is permitted up to 1000 m elevation and 55 °C ambient with derating, while nominal operation remains at 45 °C. Field wiring is secured by 3 Nm DC-bus terminals and 2 Nm motor posts, while a D-Sub 15 feedback connector and four-pin screw power plug simplify connection layout. A short-circuit rating of 42 kA aligns the version 2 drive with common industrial feeder protection requirements.
