I have been using the G33.1 rigid tapping cycle on my minimill, where I have used one of my brush PWM servo amplifiers to drive the DC spindle motor. A recurring problem I am having is the servo amp gets an overcurrent fault trip when reversing the spindle. The curious thing, though, is that it is ALWAYS when the cycle is finished, and it is going back to clockwise after backing the tap out of the hole. (Fortunate that it is this way, too!) Anyway, is there a way to reduce the rate at which the spindle reverses? Right now, it appear the spindle is ordered to slam from commanded speed forward to reverse and then back again with no acceleration at all.
