Product Description:

The HDS03.1-W075N-HS09-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. As part of the DIAX04 controller family, this unit is installed in modular multi-axis cabinets where it acts as the regulation section for servo drives. Its purpose in industrial automation is to convert command data from a motion processor into precise current and velocity control for connected motors, ensuring coordinated movement across a machine line. This arrangement supports synchronized axis behavior in machines that rely on multiple servo channels.

For power handling, the controller supplies a continuous output of 75 A, which supports high-torque axes without causing thermal overload. Cooling is managed by a built-in air blower that draws cabinet air through the heat sink, so no external fan modules are required. Reliable operation is specified within an ambient range of +5 … +45 °C, and the drive should be derated outside this window. The enclosure carries a protection rating of IP 10 according to DIN 40 050, giving basic shielding against accidental contact when mounted inside a panel. Installation is approved up to 1000 m above sea level, while full output is maintained within that altitude range.

Communication with higher-level motion controls occurs over the SERCOS fiber-optic interface, allowing deterministic cyclic data exchange for coordinated control. When cabinet temperatures are managed correctly, short-term operation can extend to +55 °C with proportional current reduction, which provides limited headroom during brief heat spikes. During logistics or plant shutdowns, the electronics remain stable between -30 … +85 °C. Internal insulation is rated to class C per DIN VDE 0110, supporting the elevated temperatures that accompany fast current changes. The controller is part of Line 03 and Version 1.
