Product Description:

The HDS03.2-W100N-HS55-01-FW is a modular axis drive controller designed by Bosch Rexroth Indramat for the HDS Drive Controllers series. It supervises power modules in multi-axis arrangements, translating high-level motion commands into regulated currents and voltages for servo and main-spindle motors while coordinating feedback processing for stable axis response. Within an automated line, the unit maintains accurate speed, torque, and position for equipment such as packaging cells, printing presses, and material-handling gantries while fitting directly into standard control cabinets.

Communication with the motion control system is handled over the SERCOS fiber-optic ring, so cyclic setpoints, actual values, and diagnostic messages are exchanged in 1 ms telegram cycles without separate fieldbus hardware. The supervised power section can provide up to 100 A of continuous output current, which is the sustained motor load supported by the paired inverter during ongoing operation. Thermal limits are moderated by a built-in air blower, which pulls cabinet air through the heat sink to keep semiconductor temperatures within range when the controller is mounted beside other modules. The device belongs to the DIAX04 family, and revision 2 introduces updated gate-drive circuitry while preserving compatibility with established system architectures.

The module is part of Line 03 and uses the mechanical format common to this drive platform. Its screw patterns and bus connectors match the cabinet layout used by related modules, which helps keep multi-axis assemblies orderly and connections properly aligned across the drive row. The housing and connection arrangement support direct installation in grouped control sections, and the controller continues to serve coordinated servo and spindle applications that require regulated current delivery and consistent signal exchange.
