Product Description:

The HDS04.2-W200N-HT79-02-FW is a modular axis drive controller produced by Bosch Rexroth Indramat for the HDS Drive Controllers series. It mounts in DIAX04 automation racks and receives cyclic set-point data from a higher-level motion processor. The controller then regulates the connected power stage so servo motors can follow commanded speed and torque profiles in packaging lines, material-handling systems, and machine tools. The unit serves as the link between centralized motion logic and the motor-side power section. This arrangement lets multiple axes operate from a coordinated rack-based platform without placing the full control function at each motor location.

This controller supplies a continuous output of 200 A, which allows it to support heavily loaded servo axes when matched with the proper power section. Communication with the supervisory CNC or PLC is handled through the fiber-optic SERCOS interface, allowing deterministic exchange of command and feedback data. Thermal management is provided by a built-in air blower that moves cabinet air across the heat sinks. This cooling method supports sustained operation in enclosed industrial cabinets. The unit is Version 2, indicating the second design release of this controller format.

Within the product range, the unit is identified as Line 04. It is classified as an HDS Drive Controller, which places it in the rack-based drive group used for closed-loop axis control. In operation, the controller acts as the regulated interface between the motion platform and the electromechanical load, so commanded torque and speed values can be applied accurately across coordinated machine axes. Its rack-mounted format also supports organized integration with companion supply and control modules in the same enclosure. This layout helps maintain orderly module placement and consistent signal routing across the drive cabinet.
