Product Description:

The HDS03.2-W100N-HS77-00-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. In a multi-axis automation rack, it acts as the central power and control stage for servo and spindle axes rather than a standalone motor module. The unit converts real-time command data from a higher-level control into regulated current and closed-loop axis response for positioning, speed regulation, and torque control. That operating role makes it suitable for CNC machinery, transfer systems, and material-handling equipment that depend on coordinated motion across several axes.

This unit delivers a continuous output of 100 A, allowing it to support medium-to-high power motor applications without current derating. Command data reach the controller through the SERCOS fiber-optic interface, which keeps cyclic communication deterministic and allows synchronized axis updates. Internal heat is removed by a built-in air blower that moves cabinet air past the heat sink, so no external ducting is required for normal cooling. The controller belongs to the DIAX04 platform, and hardware Version 2 provides additional memory capacity for stored parameter sets while keeping the same electrical footprint as earlier releases.

The unit occupies Line 03 in the rack, which helps place it correctly in systems that use several coordinated modules from one supply section. Power terminals, optical routing, and diagnostic LEDs follow the standard front layout used by the platform, so the connections remain orderly in dense cabinets. Its rack format also supports alignment with neighboring modules that use the same mechanical arrangement. The controller is intended for rack-mounted servo and spindle systems where organized cable paths, stable airflow, and consistent module placement are important during continuous industrial operation.
