Product Description:

The HDS04.2-W200N-HS27-01-FW is a digital drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. In multi-axis automation racks, the unit serves as the link between higher-level motion commands and motor response by regulating power for connected servo axes. It converts setpoint data into pulse-width-modulated output, allowing accurate positioning, stable speed control, and coordinated load sharing in industrial machinery. Because feedback values are processed inside the control loop, the controller can correct deviations in speed and position as operating conditions change. This makes the unit suitable for packaging, handling, and machine-tool systems that rely on repeatable servo behavior.

Communication with external control platforms occurs through the SERCOS optical ring, which supports deterministic fiber-optic command exchange and synchronized sampling between the controller and the motion system. Fiber-optic transmission also helps maintain reliable signal quality in electrically noisy industrial cabinets. Thermal management is handled by a built-in air blower, so component temperatures stay controlled during continuous duty without added cabinet ducting. The controller can source up to 200 A of output current for high-torque axes, which suits demanding servo applications that require sustained current delivery. The designation 04 places the unit in Line 04 of the HDS range and matches the housing format used by related modules in the same mechanical group.

Within the broader DIAX04 platform, the device is listed as Version 2 and uses updated gate drivers. This version remains compatible with earlier rack assemblies in the same platform. The controller is intended for coordinated servo systems where multiple axes share a common structure for communication and power handling. Stable current regulation and predictable module behavior are important when several drives operate from the same rack architecture. That arrangement supports synchronized motion tasks such as indexing, interpolation, and regulated speed changes across connected axes.
