Got a meter handy? measure the voltage at terminal one. You may have a voltage drop in a bad wire or connection.

EDIT: By "turning one off" did you actually re-wire the circuit such that only one LED is being powered? Just thinking out loud...
 
500ma should be enough, the 24V LEDs only draw 26ma.

Oh, I know the PS has enough juice, just thinking a loose connection or some other type of high resistance/voltage drop is all.

Yeah I'm not sure. Ill open it up and check it with a meter Saturday.
By switching off I mean one led comes on with power one from estop. No change when the stop is pressed cutting ground to the led.

Not getting a real good picture in my head. Maybe you could jot down your schematic on a piece of paper and email it to me?

Green led (pwr indicator) comes on when control panel is live via key switch. Red e-stop light is controlled by a contact block on the estop switch. When switch is depressed the light turns off. Same pwr source for both led. Same ground for both led's . separate switching via contact blocks on key on, and estop.
Separate note. still need to get a braking resistor to get the motor stop time to 1 second rather than 3.

Sounds ok. I have my e-stop LED on regardless of switch position. Still think you may have a voltage drop somewhere. ;)

Given the low mass of a mill spindle vs. that on a lathe, you probably don't need a braking resistor on your mill. Try it and see. Worst thing that can happen is the VFD throws a fault code.
 
Got a few projects coming up on the lathe soon that required a tooling upgrade. So out with the 5/16 indexable cutters in with 1/2" cutters. Only problem is that my old 3/8ths boring bar holder didn't fit my new 1/2" boring bar, and the 1/2" turning tool holders weren't deep enough to hold the flats safely. So i modified the boring bar holder to accept the new 1/2" bar.

New bar in 100 series holder. Not a great fit..

Love this machine!

Also, about the led problem. Im only getting 21 volts at the vfd.

Nice mod on the holder. I know you know this, but that holder isn't going to be real rigid. No hogging cuts! ;)

21 volts is a bit low. Is that with everything disconnected, i.e., no-load?
