HDS03.2-W100N-HS78-00-FW Bosch Rexroth Indramat

Product Description:

The HDS03.2-W100N-HS78-00-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series, which forms the servo-amplifier branch inside the DIAX04 modular platform. Designed to convert rectified DC-bus energy into three-phase motor currents, the unit regulates torque, speed, and position for a single axis in industrial automation cells.

Command data reach the controller across the SERCOS fiber-optic ring, allowing deterministic 2 ms cycle times between drives and the main PLC. Within the DIAX04 family, this model occupies the power slot for medium-to-high current axes; its output stage is rated at 100 A, so appropriate cabling and fuses must be selected. Thermal loads are handled by a built-in internal air blower, which draws cabinet air through dedicated channels instead of relying on external fans. Hardware compatibility is linked to Line 03, meaning backplane connectors and firmware are matched to that generation.

Firmware is loaded on a removable memory card, and the hardware is designated as Version 2, indicating revised IGBT gating and diagnostic circuits compared to the first release. As part of the HDS Drive Controllers series, the unit shares status LED conventions and fault codes with companion supplies, simplifying maintenance. The module is formally classified by Bosch Rexroth Indramat as an HDS Drive Controller, so parameter files created for earlier devices remain compatible. The name Bosch Rexroth Indramat also appears on the identification plate, ensuring traceability in multi-vendor cabinets.
