I think you are correct Dave, I have no electrical schema but with the tiny bit of information I can find in the old manuals these are for the Bosch system and the spindle motor is controlled by one of the Bosch modules. I think these wires went to the ASM module, got to check that up. Maybe I need to get them back in the system again, I need to figure out how to get the motor to a complete stop without burning my VFD (and how to crawl to a known position for a tool change). Oh, BTW. I document my retrofit with images as much as possible. Mostly to help others jump the bridge. You can find the images here. http://bit.ly/GAwTyg ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
