Product Description:

The HDS04.1-W200N-HT04-01-FW is a modular drive controller produced by Bosch Rexroth Indramat. As a drive controller, it supplies regulated power and closed-loop vector modulation to servo axes in automated machine tools, material-handling cells, and assembly systems. Integrated within a multi-axis rack, the unit receives motion commands digitally and delivers controlled current to motor windings. Because it works as part of a rack-based drive system, it supports coordinated speed, torque, and position control across several machine axes. The controller serves as the electrical interface between higher-level control hardware and the motors that execute programmed motion on the machine.

Communication with the supervising CNC or PLC is handled through the SERCOS optical ring, which eliminates analog wiring and supports deterministic position updates. That arrangement reduces point-to-point signal connections and keeps command exchange consistent during fast axis updates. Thermal management is provided by a built-in air blower that circulates cabinet air across the heat sink, so no external cooler is required. This helps the rack maintain stable thermal conditions during sustained output. The power section is rated for a continuous output of 200 A, allowing the controller to drive large-torque motors during rapid acceleration. The unit belongs to the DIAX04 family and occupies rack slot 04, which corresponds to the connector orientation and mounting depth used in the multi-axis package.

The controller is Version 1. It is classified as an HDS Drive Controller, so its safety relays, DC bus sharing links, and encoder feedback ports match the rack format used by companion axes. The module uses closed-loop vector modulation to regulate motor current during changing load conditions, and its modular layout keeps power and feedback connections organized inside the rack. The shared rack format also keeps interconnections short between neighboring modules, which supports compact cabinet layouts. It is part of the HDS Drive Controllers series, where multiple axes are arranged in a common enclosure for coordinated machine motion.
