CNC Part 1 (NCK, PLC, drive)
Commissioning Manual, 11/2006, 6FC5397-2AP10-2BA0
Note
The current, minimum and maximum utilization of the NCK is displayed.
In order to have sufficient reserves for program processing, maximum utilization in reset
condition when pressing the <Reset> key should be in the range of 60-65%.
The capacity indicator MD28060 NUM_IPO_Buffer_SIZE is indicated in %.
This display indicates whether batch preparation for batch processing can commence.
A jerky processing in track control, if for instance a number of short traversing sets have
been programmed in succession, is a typical indicator of the IPO buffers becoming full.
Capacity indication is channel-specific.
