Product Description:

The HDS04.2-W200N-HT75-01-FW is a modular motion-control drive produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It mounts in a DIAX rack alongside power supplies and axis modules, converting digital commands into regulated current for synchronous and induction servomotors. Within an automated cell, the unit bridges CNC or PLC motion programs to the motor windings and closes the torque and velocity loop required for precise positioning and coordinated multi-axis interpolation. This allows the drive to support synchronized movement on machine tools, packaging lines, and other equipment that depends on accurate axis response. The controller’s logic section also handles diagnostic reporting, parameter storage, and fault shutdown to protect connected machinery.

Communication to the drive is handled through the SERCOS fiber-optic interface, allowing high-speed deterministic exchange of setpoints and status with compatible motion controllers. The unit is part of the DIAX04 controller family, so its parameter structure and mechanical dimensions match companion modules in that platform. A continuous output capability of 200 A lets the controller energize large torque motors without external boosters, while duty-cycle monitoring helps prevent overcurrent events during demanding motion profiles. Thermal management relies on a built-in air blower that channels cabinet air across the heat sink fins and keeps the module within its rated temperature range under sustained loads. This cooling method removes heat without requiring a separate external fan assembly for the drive itself.

Within the product hierarchy, the unit belongs to Line 04, which places it in the fourth design line for this controller platform. The controller is Version 2, which identifies the current product revision for this model. Its mounting height, bus bar spacing, and power connector geometry match the layout used by this line, so the module fits the intended rack arrangement without extra hardware. This revision also uses the parameter ranges and diagnostic set assigned to the model.
