HDS03.2-W075N-HS78-00-FW
The HDS03.2-W075N-HS78-00-FW is a drive controller produced by Bosch Rexroth Indramat for multi-axis industrial automation. It serves as the axis power amplifier inside DIAX04 modular drive racks, translating network commands into regulated current for servomotors. In operation, the controller regulates motor current so the connected servo can follow commanded torque and speed with stable closed-loop response. This allows coordinated, closed-loop motion in packaging, printing, and material-handling systems. Its modular format fits rack-based drive systems where several axes share a common supply section.
This controller exchanges real-time setpoints and status data over the SERCOS fiber-optic bus, so it can be synchronized with other axes at a 62.5 µs telegram rate. Motor windings may draw up to 75 A of output current, which suits medium-power servo modules in this platform. Thermal energy from the power stage is removed by a built-in air blower, allowing dense mounting without an external heat sink. Within the DIAX architecture, the device belongs to Line 03, and its control logic is matched to the DIAX04 controller family. This keeps the connectors, diagnostic indication, and parameter structure aligned with related modules.
The unit is Version 2, and its gate-array logic supports faster error detection. A standardized backplane lets the axis slide into a common power bus without individualized wiring. The common bus arrangement reduces separate power wiring between neighboring axes and keeps the module layout compact inside the cabinet. As part of the HDS Drive Controllers series, it uses the same mechanical mounting pattern found across related modules. Addressing, parameter memory, and mechanical dimensions stay consistent within the same rack architecture, which helps keep multi-axis layouts orderly during installation and system expansion.
