We now have an answer to this!
Inside this file:
C:\KRC\Roboter\Init\emily_drv.ini
There is a parameter:
MAX_NUM_DATA = 27500 ; The maximum number of sampling points (default 50000 = 10min at 12ms IPO sampling rate)
Every table that is loaded will allocate enough memory for 50000 llines in the table regardless of the table size.
Later versions on KRC4 address this limitation by allocating memory per the size of the table.
You could safely reduce this to: 5,000 or even less if you know your pathtable lengths are well defined.
5000 lines would allow for up to a 1 minute table.
Then cold-reboot.
