I am a student at a tec. high school, and I run a dynapath mill with some electrical issues. One my emergency stop cuts all power to the cervo motors, but not to the spindle (this is probably due to my mill having an aux. spindle controll.) This is a major safety issue to people who are not familar with this machine. The dynapath did not come with a wiring schematic (it was donated) so i do not know where to go from here. Any information is help full then none. Is there is any where i can obtain a wireing schematic? Last my coolant switch does not function and the pump is stuck on (better then off) so to stop the flow of coolant i have to shut off the valve itself which puts unnessisary strain on the pump.
PLEASE HELP! (atleast try)

Without schematics you may have to do some reverse-engineering, what kind of spindle motor is it? 3ph, 1ph etc. How is it powered up right now? if it has a relay or contactor then you can wire this in to the e-stop contactor or relay.
Same with the pump, (reverse-engineer) although with a centrifugal type pump, shutting the flow off actually decreases the current, but a side effect is possible temperature rise.
If it is immersed in coolant, this may not be a problem.

I will look for the Motor type tomorrow. Another complication with this machine is its a Frankenstine. From the information i have gathered it takes componets from 3 diffrent machines, but i know for a fact it uses a Autocon Delta controll. The controll is an 40m, 50m, or 60m. i dont know how to find out which one it is. The only document that came with it was an operators manual for the controll.
