HDS03.2-W100N-HT74-01-FW
The HDS03.2-W100N-HT74-01-FW is a modular drive controller developed by Bosch Rexroth Indramat within the HDS Drive Controllers series. As a digital drive module, it supplies regulated power to connected servo axes and serves in multi-axis racks used in automated machinery. By managing current, velocity, and position loops, the unit works with higher-level motion controls to execute precise industrial automation tasks. The controller occupies a single slot and connects to the shared DC bus through rear connectors in a compact rack layout. This arrangement supports cabinet systems where several axes operate from common power infrastructure.
At the control interface, the unit communicates through the SERCOS fiber-optic bus, allowing deterministic exchange of real-time setpoints and feedback. As part of the DIAX04 family, it is mechanically and electrically compatible with related drives, so mixed-power racks can be assembled without adapter plates. Thermal management is handled by a built-in air blower, keeping cabinet airflow separate from the module circuitry. The power section is rated for 100 A, and the designation 03 identifies the line revision used for this controller. Its communication path supports synchronized command timing and fast feedback updates across the rack.
Control behavior is identified by Version 2, which marks this revision of the module. The controller supports diagnostic messaging for operating status and fault reporting, and it also supports axis synchronization for coordinated motion across multiple axes. A retained parameter set can be accessed through the service interface, allowing application-specific operating values to remain available when the unit is configured. These functions support stable communication, coordinated motion, and consistent drive operation in demanding automation systems.
