Product Description:

The HDS03.1-W100N-HS76-01-FW is a drive controller manufactured by Bosch Rexroth Indramat. It functions as the power and control stage for servo axes in multi-axis systems, converting drive commands into regulated motor current. This allows connected motors to deliver controlled torque and speed during indexing, positioning, and continuous-motion tasks. By regulating current rather than applying raw supply voltage, the controller helps the drive system respond accurately to motion commands in automated machinery, packaging equipment, and material-handling stations.

The controller communicates with higher-level motion processors through the SERCOS fiber-optic bus, allowing deterministic cyclic exchange of setpoints and feedback over a noise-resistant link. The optical interface also supports synchronous command timing across linked axes. Its nominal output capability is 100 A, so the unit can energize medium to large synchronous or induction motors without external booster modules. Thermal management relies on a built-in air blower, and the fan forces cabinet air across the heat sinks to keep semiconductor temperatures within safe operating limits during sustained current demand. The product belongs to the DIAX04 family and uses the mechanical format common to that platform. The product is part of Line 03 in the series.

The drive controller is Version 1. It pairs with HMS or HVE power supplies and can be rack-mounted beside other axes in the same control cabinet. The unit includes LED status reporting and an RS232 service port for local diagnostics and parameter access. The status indicators provide a quick view of operating state, fault presence, and communication activity. It is part of the HDS Drive Controllers series and uses the connector layout common to that platform, which supports compact multi-axis cabinet designs and orderly wiring between adjacent modules.
