over travel in x at reference

[Don H]

It's a Hardinge Talent 8/52 with a Fanuc 0i-TC control

I was getting a servo alarm at start up that fixed itself with a reboot.......Now the X axis will not reference do to overtravel alarm 500.

Is this over travel the hard stop or is it a soft stop from the parameter settings?

What parameter sets the over travel in x?

Could my problem be that the hard stop and the soft stop are set too close together?

Or could the ard stop just have moved?

Thanks.

If you are seeing a software overtravel, press 'Cancel' & 'P' on power up.
I believe this works on the i series, but have never really tried it.

Thanks for the reply Al...........

Start up is fine.

After start up the next task is to reference the machine. Handle jog -1.0 in x and -1.0 in z. Reference x first and I am getting an error for over travel. Not sure if the error differentuates between hard stop or soft?

Hard overtravel switch can be seen by the I/O status on either the diagnostic, or ladder, if you have it enabled.
