Hello guys:
My FANUC 21iT do not display anything when I turn it on. I checked out the fuses and they are ok, into the cabinet I found a "--" sign blinking at the spindle amplifier module. At the back of LCD display (at the panel) I noticed that the green LEDG2, 3 and 4 leds were blinking, also the red SYSFAN led.
The operator told me that there were electricity low tension (less than 380V)the past days and every time it occured the machine turn off.
¿Could be a serious damage? (where I live there is no FANUC technical assistance)
So, please, any ideas will be helpfull.
Thanks.
