Product Description:

The HDS04.2-W200N-HS78-00-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. As a multi-axis control module, it coordinates power sections within DIAX04 automation racks and serves as the control point between the machine and connected servo axes. In a production cell, it links motion control software to the power electronics and translates network commands into regulated armature current so connected machinery can follow programmed motion profiles. This operating role supports synchronized movement in equipment that depends on repeatable torque and velocity control across multiple axes.

Within the rack, the unit communicates over the SERCOS fiber-optic interface, allowing deterministic exchange of setpoints and feedback with higher-level controls. Thermal management relies on a built-in air blower that forces cabinet air through the heat sink to keep semiconductor temperatures within limits during continuous duty. The module has a rated current of 200 A, so the power stage can deliver that armature current to a motor when ambient limits are observed. This arrangement supports stable closed-loop operation where sustained motor demand and frequent motion updates occur during normal machine cycles.

The unit is Version 2 and part of Line 04. These identifiers indicate the product generation used for this drive type and separate it from other releases in the same platform. The controller is intended for rack installation and for use in systems that rely on consistent axis regulation from a centralized drive assembly. Its layout suits the rack format used by this product family and keeps the control stage integrated with the surrounding drive modules. It is suited for automated equipment where multiple servo axes must respond to coordinated commands from the machine control.
