I agree with Andy. I put my controllers on a UPS and then have a signal
that is wired through a drop-out relay that is also connected to the
emergency stop switch. So when the power fails the machine is stopped
and you can record line numbers at least and then shut down.

My question is, *should* a controller such as this have an
uninterruptible power supply? If so, what parts of the machine are
normally served by a UPS?
I doubt that it is common to attempt to machine on standby power, but
I can see good reasons to try to keep the controller alive to perform
a controlled axis/spindle stop and graceful shutdown (including
writing to the log files, tool-table etc)
