Yes, I would think that the spindle must come to a stop within 5 degrees
of rotation from
when the overload is detected. I think that w

Sure you look at the tap before using it... if it is worn out toss it
out. New taps are much cheaper than removing a broken tap. All it takes

You can monitor motor current on any drive, sometimes it is built in
to the drive, but otherwise there are various forms of current sensing
element that can be used.
However, nothing w
Hi
i there spindle motor and motor drive that can be better used for tapping?
Problem with use tap is that spindle motor can easy crash tap and after
that extra charge - + equipment - to remove broke tap from hole.
Every one try to get max from each tap and many times tap that "look good"
