Product Description:

The HDS04.1-W200N-HS78-00-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the HDS Drive Controllers series. It functions as a power and control module that manages servo motors in a DIAX04 multi-axis system, providing regulated current and a coordinated interface between the motion controller and the mechanical load. In a multi-axis installation, it serves as the regulated drive stage between the system power supply and the connected motor. By adjusting motor torque, speed, and position in response to digital commands, the unit supports precise synchronized movement in automated machinery. This arrangement lets the controller translate command data into controlled motor action while maintaining closed-loop operation across demanding motion sequences.

The communication backbone relies on the SERCOS interface, so motion commands, parameter data, and diagnostic feedback travel through a deterministic, high-speed fiber link. The fiber-optic link also helps maintain signal integrity in electrically noisy industrial cabinets. The power stage is rated for 200 A, allowing the unit to energize large servo motors without external booster modules. That current capacity supports larger servo axes during sustained load and dynamic motion. Thermal management is handled by a built-in air blower, which channels cabinet air across the heatsink and removes the need for liquid cooling. The controller belongs to the DIAX04 family, and line code 04 identifies the mechanical size and connector layout used for this version of the module.

This release is Version 1. The drive includes gate-drive electronics, current measurement, and protective circuitry required for closed-loop servo operation. It mates directly with supply units of equal bus voltage and shares the mounting rails used in the platform. Its shared platform format lets it fit mechanically with matching supply hardware in the same system. These hardware relationships keep the module aligned with compatible multi-axis assemblies while preserving the intended electrical and mechanical fit.
