Question:

The program verification graphics of the iTNC 530 with NC software no. 340 422 is much slower than on TNC 430. How can I speed it up? 

Answer:

The newer software levels of the iTNC 530 are capable of program run simulation that correctly portrays tilting operations and multi-axis operations. This simulation model requires that the iTNC calculate the complete machine kinematics during program verification, which of course increases processing time.  

By setting machine parameter 7310=1 you can change the internal simulation model back to the older, faster method. However, tilting operations and multi-axis operations are then no longer portrayed correctly.
