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.

Jack 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? -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ---------------------------------------------------------------------------- -- EditLive Enterprise is the world's most technically advanced content authoring tool.
