You probably can set a 1 second rampdown and it won't trip, or put the

I will experiment. The issue is, obviously, higher spindle speeds,
requiring longer rampdown.


you REALLY DO NOT want a rampdown if you are going to use the mechanical
brake - set it to coast


Correct, else the VFD will be fighting the mechanical brake
