Product Description:

The HDS03.2-W075N-HS22-01-FW is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. As a motion-axis module in modular DIAX04 racks, it regulates current and velocity in servo drives used on machine tools, packaging lines, and handling systems. The unit converts DC bus energy into three-phase output for synchronous and asynchronous motors, enabling closed-loop positioning, indexing, or spindle functions within industrial automation cells. Because the controller manages both current and speed loops, it suits coordinated axes that must respond quickly to changing load conditions during production.

The module exchanges setpoint and diagnostic data over the fiber-optic SERCOS interface, allowing deterministic communication with PLCs and CNCs. It belongs to the DIAX04 controller family, so it shares parameter structure with other axes in the rack. Continuous motor demand is supported by a 75 A output stage that maintains torque during rapid acceleration cycles. Cooling is handled by a built-in air blower that draws cabinet air through the heat sink and helps prevent performance loss at full current. A front-panel gasket and housing perforations provide an IP10 protection category, which helps guard live parts against accidental contact while still permitting airflow. The optical communication path also reduces susceptibility to electrical noise in cabinets with multiple power devices.

Thermal and dielectric limits govern the allowed operating conditions of the drive. Windings and power semiconductors use class C insulation under DIN VDE 0110, allowing higher internal temperatures before breakdown. Reliable operation is specified for ambient conditions between +5 to +45 °C. Above that range, the controller can still operate with derated output up to +55 °C. When the machine is idle, the unit withstands storage temperatures from -30 to +85 °C without damage. Installation is approved up to 1000 m above sea level, and the Line 03, Version 2 design uses the same rack footprint as other modules in this product line.
