Product Description:

The HDS04.2-W200N-HS78-01-FW is a modular drive controller produced by Bosch Rexroth Indramat for use in multi-axis automation racks. As part of the HDS Drive Controllers series, the unit coordinates inverter power stages and servo feedback loops so industrial machinery can carry out position, velocity, and force commands with closed-loop accuracy. In packaging lines, machine tools, and material-handling cells, it works as the central axis card that conditions command signals and forwards them to connected power modules. Because the controller processes commands and feedback within the rack, it supports stable axis response during continuous production cycles. This layout is suited to systems that need synchronized motion across several connected axes.

Its real-time command channel relies on the SERCOS fiber-optic interface, enabling deterministic data exchange between the controller and higher-level PLCs. Within the DIAX04 control family, the unit uses size W and belongs to the second mechanical generation. The drive supplies up to 200 A of continuous current to compatible servo or spindle units, so associated cabling, busbars, and protective devices must match that load. That current capacity suits larger servo applications that require sustained torque rather than brief peak output alone. Thermal loading is managed by a built-in air blower, which recirculates cabinet air through the module to support heat removal.

The unit is Version 2. It operates as an HDS drive controller, and when installed on a common DC bus, it can share regenerated energy with neighboring axes in the rack. This arrangement helps balance energy flow during acceleration and deceleration in multi-axis systems. The rack-based format also allows the controller to work alongside companion modules that provide the required power conversion and related system functions. Integrated diagnostics remain available through the established system interface for status and fault monitoring.
