I was starting large saw blades. 120" Diameter. The ramp time was crazy important. If you allowed the system to start in a linear ramp function the blade would hit a harmonic that would cause it to throw carbide inserts. When we let it start with a current limit and it got to through the harmonics much faster. I can't say for sure why the harmonic stayed so long in time based start but it did.
