Re: [Emc-users] What does these do?
2013/10/3 Sven Wesley svenne.d...@gmail.com 2013/10/3 Dave Cole linuxcncro...@gmail.com Probably braking resistors for the spindle. The resistors are connected across the 3 phases of the motor to bring the motor to a rapid stop. Looks like they are wired in a Wye or Star connection..One center connection and the three phases which probably connect to a contactor which is connected across the motor during rapid braking. Dave I got an answer from a service company that is specialized on these machines. They are braking resistors for the servo's, that's why there are nine of them (three for each motor).

Dave 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.

[Emc-users] What does these do?
Power up brakes? There were nine of these at the power source side in the mill I am retrofitting. They are grouped in three. I guess they have something to do with the power-on process. Or energy dumping when stopping the spindle. On top of that I have no idea why they are connected like this. Please enlighten me!
