Thanks for your response
x8.4 is on but g8.4 is off

Can you see what in the ladder is preventing G8.4 from coming on? You need to search for the coil in the ladder.

do you have a pdf document with your electrical diagram?
or open the electrical diagram and in 1 page should be the entire emergency circuit,make a photo and post it.

The problem is these connections are variables. That mean it all depends on how the I/O assignments has been laid out. Fanuc states in this example:


Xm+0.0 M= starting address for this address. So if your starting address is X8 this pin would be X8+0.0 or X8.0
Hope that helps.

Hi!!!
I have a similar problem with a Nakamura Tome TMC-12 Control Series 21-T, this machine was working well, until a technician came to check a vibration in the Z axis servo, apparently it loaded parameters and the machine did not return to work, I have a backup of the machine parameters, I reloaded them, no alarm comes out, but it is in EMG state, I can navigate the menus, but nothing else works (spindle, hydraulic system, turret , move the axes).
Hopefully someone can help me, best regards.
