Boss 5 Dirty power ?

[D.D.Machine]

My question is do I have to spend hours looking thrue the manuals trying to track down the wire to the brain when I run it off a home brew 3 phase power supply? One lead is about 10 to 20 volts HI normaly.

thanks

I've always been VERY careful not to use the wild leg on computer and other stuff that might be 110 volts. I learned the hard way when I burned up my servo powerfeed on a bridgeport.

Its not that bad a job. Hook up one leg to the hot and use one of those test lamps to find where all it goes. Then move the hot wire and repeat. Also try your estop circuit each time, it always uses just one hot leg.

There is a transformer in the lower RH when looking at the rear, it steps 220 down to 110. trace the wire back to the main fusees, don't hook the made leg to this. I think mine is the far RH fuse. I ballance my converter unloaded. Then added caps to the motor and just befor the big three phase transformer. This way the three phase is ballanced loaded and unloaded. My voltage is always within 5%.
