The SuperPID is optimized for the style of
universal motors that are typically used for 
consumer/home shop high speed wood router
spindles. The KBIC controllers are typically
designed for shunt or permanent magnet motors
though they may work OK with a universal type 
motor.

When interfacing to a KBIC style controller,
be aware that the terminals that normally go
to a potentiometer are NOT isolated from the
line voltage. An option board or a homebrew
opto-isolator will be needed.

Also, I think the SuperPID kit includes an optical
spindle speed sensor, something you would need to
rig up if you used EMC as the PID controller.

I am not fond of the idea of adding a PID controller
to a modern wood router with a universal motor. Many
of them have internal electronics for soft start,
line fail restart inhibitors, and internal variable
speed controls. These circuits will not be happy
with SCR drives feeding them.

After a _very_ brief look at the website, it looks like an SCR speed
controller with a micro-controller built on to the board. I tend to
think EMC2's HAL PID and PWM connected to a KBIC style speed controller
(universal motor speed driver
http://www.kbelectronics.com/manuals/kbic_manual.pdf 
http://www.wallacecompany.com/machine_shop/kbic/
) would do the same thing, plus integrate better with HAL, have more
configuration options, be open source, etcetera. If the firmware where
open it might be interesting to play with other options for a non-EMC2
smart SCR driver application. Maybe add a keyboard and have a stand
alone smart universal motor controller?
