HDS03.2-W075N-HT73-01-FW
The HDS03.2-W075N-HT73-01-FW drive controller is produced by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. It forms the control section of a DIAX04 modular drive stack and converts digital motion commands into regulated armature current for servo axes used in packaging lines, machine tools, and handling stations. In automated equipment, it serves as the link between higher-level motion control and the connected motor. Its role is to coordinate torque, speed, and position loops so that connected axes follow commanded motion with repeatable accuracy under changing load conditions.
Its command channel is the SERCOS interface, a real-time fiber-optic network that transmits setpoints and status data in deterministic cycles. This communication method supports synchronized command transfer and quick status updates during continuous machine operation. As part of the DIAX04 platform, the controller shares mechanical and electrical compatibility with common power supply modules and auxiliary cards installed in the same rack. The controller can sustain a continuous motor phase current of 75 A, allowing it to drive medium-to-large servomotors without external boosters. Thermal energy is removed by a built-in air blower, which moves heat away from the power section and supports reliable operation in enclosed cabinets. The product is part of Line 03 in the series.
The drive controller is Version 2. It uses a consistent connector pinout across the range, which supports orderly integration with matching system modules and cable sets. The front-panel diagnostic LED pattern provides clear status indication during startup and normal operation. Its regulated current control supports accurate motor response during acceleration, steady-speed travel, and position correction under changing load conditions. This helps the axis maintain stable behavior when motion profiles require repeated starts, stops, and speed adjustments.
