Fanuc 10T E Stop Shuts off Control

[charger19690]

Hello,

We got an older Nakamura Lathe with a Fanuc 10T Control on it.

We received it a year ago from which it was stored outside covered.

We have been fixing gremlins as we go, but one issue we are having it Loading Parameters via the RS232.

The problem isn't communication, it's the E Stop button. For some reason this lathe when E Stop is hit, shuts down the Control.

Is this something with this model lathe/control or is it an issue with this particular lathe. I have never seen a machine shut down when E Stop is pressed, just the hydraulics and the servos.

Any help would be great.

it is possible that the e-stop is wired to turn the control off (definitely not normal) but more likely the +24V is shorting out to ground when the button is pressed.

I have only seen it once before where the MTB, Butler from UK implemented the same feature, which is a PITA, it is customary to keep the control live and even the Inputs, just shut of the outputs, drives and motors.
The CNC side shuts down via the E_stop input.
I have always set up the E-Stop this way.

Well the machine is from Canada, so who knows what they do up there...lol

Anyways, is this probably a hard wire issue, versus something that is driven by a parameter?

Ah so desu Ka, Nakamura es Japanese Co.

But it should not be hard to change, just take the power to the controller out of the E_stop loop.
IOW ensure the power is on the CNC control board when the E-Stop is implemented.
There is a dedicated input for E-stop which you may or may not have to provide and input, depending on how it is presently connected.

Oh, I hope you didn't think I meant it was made in Canada, just that we got it from a Canadian company...

Anyways, I am not sure I am up to the challenge of playing with the wiring, but maybe the next time we have our tech come in I will see if he could make any sense of it.
