HDS04.2-W200N-HS94-01-FW
The HDS04.2-W200N-HS94-01-FW drive controller is manufactured by Bosch Rexroth Indramat and belongs to the HDS Drive Controllers series. Installed in centralized automation cabinets, the unit distributes DC-bus power and monitoring functions to attached servo inverter modules. It coordinates motion sequences, reports diagnostic data to the machine control, and helps protect downstream axes from overcurrent or thermal faults. This makes the controller suitable for high-performance CNC, packaging, and material-handling systems.
At the power end, the controller can deliver a continuous output of 200 A, allowing it to energize large-torque motors without saturating the DC link. Command data reaches the module over the SERCOS fiber-optic bus, and this deterministic channel carries position setpoints and real-time status with sub-millisecond latency. This arrangement supports synchronized communication between the controller and connected axes during rapid changes in speed or position. Thermal management relies on a built-in air blower that draws ambient air through the heat sink to keep semiconductor temperatures within safe limits. The unit belongs to the DIAX04 controller family and is part of Line 04, matching the electrical backplane pinout and mechanical mounting dimensions used throughout the family.
The unit is Version 2, which keeps motion-command scaling and diagnostic code handling consistent across machines in the same control generation. The device is classified as an HDS Drive Controller, which means it does not include an integrated power supply or axis inverter hardware on the card itself. The embedded command communication interface negotiates ring configuration automatically during power-up, so the controller can join the optical ring before cyclic data exchange begins.
