HDS03.2-W075N-HS77-00-FW
The HDS03.2-W075N-HS77-00-FW is a drive controller manufactured by Bosch Rexroth Indramat and supplied in the HDS Drive Controllers series. Within an automation rack, it conditions power and executes motion commands so connected servo axes can follow precise velocity and torque references. By accepting setpoint data from a central PLC and supervising feedback loops, the unit supports coordinated multi-axis operation in assembly lines, packaging machines, and material-handling cells. This operating role places the controller between higher-level motion commands and the electrical power delivered to the drive system, so it functions as both a control element and a power-handling module inside a modular cabinet.
Data exchange to higher-level controllers is handled through the SERCOS fiber-optic interface, allowing deterministic synchronization of motion tasks over a real-time network. The power stage is rated for 75 A, so it can supply this continuous output current to downstream drives under nominal conditions. Thermal regulation depends on a built-in air blower that draws cabinet air across the heat sinks to keep semiconductor temperatures within a safe range. The mechanical format aligns with the DIAX04 controller family, and the unit is part of Line 03, which supports use in modular rack layouts built around that platform.
The controller is Version 2. When installed with related modules, power sharing and regenerative energy handling are coordinated through common DC links, allowing energy to move across the rack during acceleration and braking cycles. Its mounting, busbar spacing, and wiring conventions match the platform used by this product line, which helps keep cabinet integration orderly. The unit also follows the standard connection approach used across the platform, so signal routing and power distribution remain organized in multi-axis assemblies.
