Product Description:

The HDS03.1-W100N-HT04-01-FW is a drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. The unit converts motion commands into regulated three-phase current for servo axes in automated machining centers, packaging lines, and material handling stations. When combined with a compatible modular power supply, it closes the current loop and supports coordinated multi-axis movement required for precise industrial automation tasks. This makes it suitable for applications that need stable torque delivery, controlled speed changes, and accurate response to command updates during continuous machine operation.

The command interface is SERCOS, so motion data moves over a fiber-optic ring with consistent timing and good noise immunity. As part of the DIAX04 platform, the module shares a common connector layout with other axes in the rack. Thermal management is handled by a built-in air blower, which draws cabinet air across the heat sink during full-load operation. The continuous output capability reaches 100 A, allowing the controller to operate medium-to-high torque motors without derating. This cooling method supports cabinet installation where airflow must pass across the power section without requiring liquid cooling.

The product is part of Line 03 and is released as Version 1. These identifiers indicate the design line and release level used for this unit. Shared status words across the rack help coordinate power modules, axis cards, and feedback interfaces during synchronized multi-axis operation. Its layout also supports use in modular drive systems where several controlled axes must exchange operating information through a common control structure. Because the optical command path is isolated from power wiring, communication remains clear in electrically noisy machine cabinets.
