HDS03.1-W075N-HS94-01-FW
The HDS03.1-W075N-HS94-01-FW is a modular drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. In a DIAX04 multi-axis rack, it serves as the power and regulation stage for compatible servo axes. By converting incoming DC bus power into timed output pulses, the unit supports closed-loop torque and velocity control for handling gantries, packaging lines, and metalworking equipment. Its modular layout suits centralized automation cabinets where several axes share one coordinated drive platform. That role lets the controller respond quickly to command changes while maintaining consistent drive output during repetitive machine cycles.
Its continuous output capability is rated at 75 A, so the power section can supply attached motor modules without derating under nominal conditions. Command data are exchanged through the SERCOS fiber-optic interface, allowing deterministic communication for synchronized motion across multiple axes. Thermal management relies on a built-in air blower that draws cabinet air through the heat sink and exhausts it upward, which supports stable operation without external ducting. Because the controller belongs to the DIAX04 family, its backplane connectors, dimensions, and bus arrangement match related modules in the same platform. This layout helps the unit fit established rack assemblies that use shared mechanical and electrical interfaces.
The unit is Version 1 and part of Line 03, which identifies this product generation and layout within the series. It uses integrated current regulation rather than splitting that function across separate cards, and axis diagnostics are handled within the same module. The controller slides into the power supply cage and mates with the shared DC bus for rack-based installation. The rack-mounted design keeps wiring concentrated around the cabinet backplane instead of distributing power electronics across the machine. This module format supports compact control cabinets that group motion power and regulation hardware in one enclosure.
