HDS03.2-W075N-HS94-01-FW
The HDS03.2-W075N-HS94-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Mounted with a compatible power supply, it serves as one axis channel in a multi-axis drive system. The unit converts motion commands into regulated motor current for servo or spindle applications. By closing the position and velocity loops inside the drive, it allows axes to accelerate, hold speed, and decelerate along controlled trajectories in machining, packaging, and material-handling equipment. In automated lines, this arrangement lets the controller respond quickly to command changes from the higher-level control system while maintaining smooth torque delivery at the motor.
Communication with upstream PLC or CNC equipment is handled through the command communication interface, which uses SERCOS fiber-optic cabling to maintain deterministic cycle times. Fiber-optic communication also helps the controller resist electrical noise in cabinets that contain high-current switching hardware. During operation, the power stage can supply a continuous 75 A output, allowing connected axes to support rapid acceleration without thermal derating. Heat generated by switching devices is removed by a built-in air blower, which helps maintain stable internal temperatures during extended duty cycles. The controller is part of Line 03, which matches its connector pattern and mounting dimensions to other modules in the same design line.
As part of the DIAX04 platform, this controller is built as Version 2. This version indicates an updated control stage and memory configuration relative to earlier builds. Within a DIAX04 rack, the controller works with system components that provide DC-bus power and supporting functions for coordinated motion. The module format supports organized installation in machine cabinets where several controlled axes are grouped side by side. Its function remains focused on closed-loop motor control rather than integrated supply or braking hardware, so it operates with the supporting modules required by the drive system.
