Need Help! Max velocity and Acceleration - or how not to beat your ballscrews to death?

My past CNC conversions used stepper motors so were inherently slow.


My latest conversion (8x30 Knee mill) with DFU2005 and DFU1605 ballscrews uses 750W ac servos, These are a world different in terms of torque at speed and I can move the table near silently (compared to steppers) and fast, test run at 100IPM is no problem.


I would imagine the forces at the ballscrews are not trivial. So my question is if I want longevity what are good limits to place on acceleration and velocity?
