Product Description:

The HDS03.1-W100N-HT12-01-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for multi-axis motion systems. It converts DC bus energy into three-phase output and performs real-time current regulation, enabling precise torque and speed control of synchronous or asynchronous motors. Used in automated machining, packaging, and material-handling equipment, the unit links a central motion processor to field devices so multiple axes can follow coordinated motion profiles. Its integrated logic module supports parameter storage and status indication through front-panel LEDs and serial diagnostics, allowing operating data to be viewed without adding separate interface hardware. This arrangement lets the controller respond quickly to load changes during acceleration, deceleration, and steady-speed operation.

Command traffic is carried over the SERCOS fiber-optic ring, allowing cyclic setpoints and status data to move between the drive and the master controller with sub-millisecond timing. The power section is rated for a continuous 100 A output, permitting direct connection to medium-power servomotors without external boost modules. Heat is expelled by a built-in air blower, so only unobstructed cabinet airflow is required for normal cooling. The unit follows DIAX04 family conventions and is part of line 03, which identifies its design line within the series and matches the rack layout used in DIAX04 systems.

The unit is Version 1. It is classified as an HDS controller for servo axes and provides front-panel LED diagnostics for operating status, making routine state checks possible at the module face. It belongs to the HDS Drive Controllers series, which uses a modular rack format for coordinated multi-axis installations. The controller works as one section of a larger drive system, where power distribution, command exchange, and motor control are handled through the common rack structure rather than through a standalone enclosure. This format supports compact cabinet integration where several axes share common infrastructure.
