HDS03.2-W075N-HS78-01-FW
The HDS03.2-W075N-HS78-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat in the HDS Drive Controllers series. It serves as the power stage for servo and spindle motors in positioning, contouring, and feed control applications across automated assembly, handling, and machining systems. The unit converts energy from a shared DC bus into regulated motor current and supplies controlled three-phase power for coordinated axis motion. An optical communication path allows command data to move quickly between the controller and the rest of the drive system so multiple axes can remain synchronized during operation.
Its command channel uses SERCOS, which provides cyclic optical communication for coordinated drive control. The interface supports up to 32 nodes on a single ring, making it suitable for multi-axis layouts that require deterministic data exchange. The controller belongs to the DIAX04 platform, so it fits systems that share the DC link and related safety functions across adjacent modules. Continuous motor current is supported up to 75 A, giving the power stage enough current capacity for demanding servo or spindle loads. Heat is removed by a built-in air blower that moves cabinet air across the heat sink without requiring external ducting.
The unit is released as Version 2, indicating the second hardware release for this controller. It is assigned to Line 03, placing it within the third design line of the platform. This arrangement keeps the module aligned with rack-based systems that use the same design line and backplane concept. Power wiring and motor feedback connections are routed directly to the controller, while the optical command path remains part of the system communication layout. The result is a drive module intended for shared-bus installations where coordinated motion and compact cabinet integration are required.
