Product Description:

The 5AC600.HDDI-05 hard-disk module is produced by B & R Automation and belongs to the 5AC CNC Addon Modules series. Within a machine controller, this module functions as a secondary storage device and provides nonvolatile space for NC programs, operating data, and diagnostic records. By using an ATA interface, it can be mounted directly inside a panel PC or within the drive cabinet, allowing the control system to archive large data sets while the controller executes real-time motion tasks. Because it is supplied as a field-exchangeable cartridge, the module can be replaced without rewiring, which helps reduce downtime.

The storage capacity is rated at 40 GB, giving ample room for tool paths, HMI graphics, and extended log files generated during multi-shift production. An onboard 8 MB cache buffers burst transfers between the rotating media and the controller bus, smoothing reads and writes under fragmented workloads. Data moves across the bus at up to 100 MB/s, a throughput consistent with the Ultra DMA modes used by the ATA-6 protocol at the board connector. Average seek and latency are reflected in an access time of 12.5 ms, so the drive retrieves scattered blocks quickly enough for typical CNC file streaming.

The platters rotate at 5400 rpm, balancing power draw and vibration against sustained throughput. Each logical block comprises 512 bytes, matching sector sizes expected by legacy real-time operating systems used in motion controllers. From power-on, the unit reaches operating speed in approximately 3 s, which helps limit boot delays when the wider control cabinet is energized. With a mass of only 100 g and enclosure dimensions of 98 mm × 13 mm × 128 mm, the module fits standard 2.5-inch bays and adds little inertial load to slide-in carriers. Two recording heads are used, and integrated SMART monitoring provides predictive health data during operation.
