Great. Pete, there is nothing that you can possibly do to break these
drives with your Bridgeport mill, except for one thing: switch the
motor off by using your reversing switch on the mill, while the drive
is running. So keep this in mind. I am sure you knew, but I wanted to
say anyway.

The quietness factor alone is worth $120. So your speed adjustments,
and dynamic braking, are freebies.

The existing drum switch will be removed, so no chance of switching
under power. I may mount the whole VFD up in that position since it's
not very heavy. Less fab work than a swing arm. Dunno, I'll see what
makes the most sense.

I would not remove it.

I usually flip this drum switch whenever I change the mill's gearing
from main gear to back gear. That way, forward on the drive always
means forward. Think about it.
