Product Description:

The HDS03.2-W100N-HS58-01-FW is a motion-control drive controller manufactured by Bosch Rexroth Indramat. Installed in multi-axis automation cabinets, the unit converts numerical setpoints into regulated motor currents for servo and spindle axes used in machining, packaging, and material-handling systems. In normal operation, it works as the control and power stage between the machine command system and the connected motor. This allows the axis to maintain commanded speed, torque, and position while responding to changing loads and cycle demands.

This controller exchanges real-time command and feedback data over the SERCOS fiber-optic interface, allowing deterministic communication with the higher-level control. The optical link also helps reduce susceptibility to electrical noise inside dense control cabinets. It belongs to the DIAX04 family, so its mechanical outline and backplane connection match other modules in that platform. Thermal management is provided by a built-in air blower, which moves cabinet air across the heat sink without external ducting. The power stage is rated for 100 A continuous output, giving the module the capacity to operate large torque motors from a common DC bus. The unit is part of Line 03, which identifies its design line within the series.

The drive is listed as Version 2, which indicates the hardware revision for this model. This revision includes updated gate-drive logic and revised diagnostic messaging compared with earlier releases in the same product line. As part of the HDS Drive Controllers series, it uses the same general operating concept and parameter structure found across related modules. Status and fault information are reported directly by the controller during operation, which helps the machine control react to overloads, communication issues, or thermal events. The cabinet-mounted format keeps the drive integrated with adjacent axis hardware without requiring separate external cooling equipment.
