let me describe my case one by one
when the 1st time I turn on the machine, about 3-5 min the alarm show up (25 F Servo Amp X)
I checked the drive it show FIN OH Led was lit on X drive. I swapped the drive with Z drive and turn on the machine. but the alarm still on X drive position even I swapped with Z drive. So I turn off the machine, then I remove the servo motor cable for X axis.
After I remove the cable and turn on the machine the alarm didn't appear for over 1 hour.
So what is problem that makes my drive overheat?
