HDS04.2-W200N-HS12
The HDS04.2-W200N-HS12 is a drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. In an automation system, it converts DC-bus power into controlled motor current so servo axes can follow position, speed, and torque commands from a central control platform. This allows packaging, handling, and machine-tool axes to respond smoothly to changing loads during synchronized motion. It also supports precise regulation at steady speed and during rapid acceleration or deceleration. By combining power electronics, signal conditioning, and interface functions in one enclosure, the unit supports coordinated multi-axis operation while helping keep cabinet space usage under control.
Communication is handled through a SERCOS fiber-optic interface, which carries cyclic command and diagnostic data with deterministic timing. Optical communication also helps reduce sensitivity to electrical noise in high-power cabinets where motor and supply wiring run close to control hardware. The unit is part of the DIAX04 family, so it matches companion supply and feedback modules used in the same rack system. Thermal management is provided by a built-in air blower that moves heat away from the power section and supports installation inside an enclosed cabinet. The output stage can deliver 200 A continuously, giving the controller the current needed for large servo motors and demanding acceleration cycles.
The drive is Version 2, which indicates the second product revision for this unit. It is also assigned to Line 04, a designation used for this design line within the product range. Classified as an HDS Drive Controller, the unit is intended for high-power positions in the rack where smaller axes may use lower-current modules. Its enclosure dimensions and rail locations follow the same platform layout used by related modules, which helps maintain a consistent cabinet arrangement. Separate supply and feedback units can be installed beside it in the same system, allowing the rack to support coordinated multi-axis motion with distributed functions.
