Product Description:

The HDS04.1-W200N-HS37-01-FW is a drive controller produced by Bosch Rexroth Indramat and assigned to the HDS Drive Controllers series. The unit functions as an axis module within modular DIAX multi-axis racks, supplying regulated power to servo drives and coordinating motion through fiber-optic command traffic. Its role is to translate digital setpoints from higher-level controls into precise current and velocity commands for connected motors, enabling synchronized positioning, stable speed regulation, and repeatable motion in packaging stations, handling gantries, and machining centers. In a multi-axis machine, it serves as the control layer between the rack supply and the connected motor channel so commanded motion can be carried out with consistent timing.

The controller exchanges real-time cyclic data over the SERCOS interface, which carries deterministic 2 kHz telegrams for position, velocity, and diagnostic data. Compatibility with the DIAX04 family provides matching mechanical fit and connector arrangement with companion supply modules and interfaces in the same rack. Thermal management is handled by a built-in air blower, which directs cabinet air across the heat sink to support continuous operation. The controller is rated for 200 A of continuous output current, which supports axes with substantial torque demand during sustained operation. The designation Line 04 identifies the mechanical width and connector arrangement used in the rack.

Within the HDS Drive Controllers series, the module uses the shared pinout and parameter structure common to HDS axis cards. This allows it to work with matching supply and interface modules in modular multi-axis assemblies without requiring a different rack layout. The unit is listed as Version 1, which indicates the initial release of this controller variant. Because it is part of a rack-based drive system, power distribution and communication are handled through the larger platform rather than through a standalone enclosure. The card serves as the power and control stage for coordinated servo operation, processing command traffic and motor-control signals inside the rack.
