Product Description:

The HDS03.1-W100N-HS28-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Installed in a modular drive rack, it converts digital command data into regulated current for servo and spindle motors. Within automated production cells the unit supplies coordinated motion so that multi-axis tooling, material handling, and packaging modules achieve precise positioning without separate analog regulators.

The command communication interface used by this controller is SERCOS; the fiber-optic ring transmits real-time set-points and status words, eliminating analog noise and allowing up to 32 drives to share one bus. Bosch Rexroth assigns the unit to the DIAX04 family, meaning its firmware blocks, diagnostic codes, and mechanical outline match other modules in that platform for interchangeable axis combinations. Thermal management is handled by a built-in internal air blower, so cabinet designers do not need external ducting and the electronics stay within the specified temperature window under continuous current. The power stage supports a rated output of 100 A; this defines the maximum steady-state motor phase current the drive can deliver before reaching its thermal or electrical limits.

The numerical identifier reveals that the unit sits in the 03 line of the series, indicating hardware refinements in gate driver boards and sensor resolution compared with earlier releases. Firmware package level is fixed at version 1, so all parameter structures, option card mappings, and diagnostic message tables follow that single revision. Because the catalog lists no alternate versions, maintenance teams can stock a single spare without compatibility concerns. Finally, its drive controller classification makes the device responsible only for current and velocity loops, leaving motion profiles and program logic to host PLCs that issue bus telegrams.
