Product Description:

The HDS03.1-W075N-HA32-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. In multi-axis systems, it regulates current and velocity for servo drives, allowing coordinated motion in gantries, machine tools, and handling modules. Through closed-loop control, it links the central CNC or PLC to the power stage that feeds the motor windings. This arrangement lets the drive respond quickly to command changes during positioning and speed-controlled operation. It is intended for cabinet-mounted motion systems where several axes operate within the same control structure.

This controller exchanges setpoints and feedback over an analog command channel, so signal quality depends on proper external wiring. Thermal management is handled by a built-in internal air blower, which circulates cabinet air across the heat sink rather than requiring an external duct. Continuous operation is permitted up to 1000 m above sea level. The ambient operating temperature range is +5 to +45 °C, and derated operation is permitted up to +55 °C when output current is reduced. The power stage can deliver up to 75 A, which suits medium-power servo motors during acceleration and steady operation. These operating limits help the controller maintain stable performance in typical industrial enclosures.

Electrical insulation uses insulation class C per DIN VDE 0110, allowing higher temperature tolerance than lower insulation classes. The housing has an IP 10 rating according to DIN 40 050, so it should be installed in a closed cabinet to keep out dust and moisture. This enclosure also blocks accidental contact with larger objects, but it is not intended for exposed installation on the machine frame. As part of the DIAX04 controller family, the module uses backplane bus dimensions that match other compatible units in the platform. That layout supports orderly installation in multi-axis cabinets and keeps the mechanical arrangement consistent across related controllers.
