Product Description:

The HDS04.2-W200N-HS57-01-FW is a HDS Drive Controller produced by Bosch Rexroth Indramat for use in multi-axis drive systems. It serves as the power and control stage inside DIAX04 cabinets, converting DC link energy into regulated current for connected servo axes. The controller inserts into standardized backplanes, where it translates serial motion commands into precise current profiles for coordinated acceleration, deceleration, and holding functions. By regulating output current in real time, it supports stable torque and speed control as load conditions change in automated machinery such as packaging lines, pick-and-place units, and machining centers.

Its continuous output capability reaches 200 A, allowing high-torque motors to start and run without thermal derating in normal operation. Command data are exchanged over SERCOS, which provides deterministic cycle timing with 32-bit position words for synchronized motion control across the cabinet. Thermal control relies on a built-in air blower that pulls cabinet air across the aluminum fins to keep semiconductor junction temperatures within range during sustained load. The controller is part of the DIAX04 family, and the code Line 04 corresponds to the 200 mm mechanical frame and bus bar spacing used in this power class.

This unit is identified as Version 2, and updated logic arrays with faster A/D conversion distinguish it from earlier releases. Revised gate driver circuitry reduces switching losses, while an enlarged fault memory stores longer error histories for status review after a shutdown or trip event. Front-panel LEDs indicate controller status, overcurrent, heat-sink temperature, and communication readiness, so operating conditions can be checked directly at the unit. A separate X2 connector supports handheld programming units for local parameter access and service tasks.
