HDS02.1-W040N-HA42-01-FW
The HDS02.1-W040N-HA42-01-FW is an intelligent motion control unit from Bosch Rexroth Indramat in the HDS Drive Controllers series. Installed next to power inverters inside a cabinet, it interprets reference commands, supervises motor feedback, and issues gate signals that keep servo axes aligned with programmed trajectories. By processing reference inputs and feedback in the same unit, it helps the drive system maintain stable motion during acceleration, deceleration, and position holding. The controller works with neighboring drive hardware so multiple axes can respond to command changes with consistent timing. It serves as a core component in automated packaging lines, pick-and-place systems, and other machinery that depends on coordinated multi-axis motion.
The controller exchanges setpoint data through an analog command interface, so drive amplitude is varied by continuous voltage levels rather than serial words. This input method suits control layouts that generate proportional reference signals without using a digital communications channel. Thermal management is handled by a built-in air blower, which circulates cabinet air across the heat sink without external ducts. Combined with cabinet airflow, this cooling method removes heat from the power electronics during sustained operation. The power section is rated for 40 A, supplying sufficient current to medium-frame servo motors during dynamic cycles.
The unit belongs to the DIAX04 controller family, letting it share backplane buses and diagnostic functions with matching supply units. The family assignment also supports compatible cabinet integration with related drive components. The product is part of Line 02 of the platform. Its circuit board assembly is designated Version 1, indicating the first release of this hardware layout. These identifiers describe the controller revision used for this model.
