I am looking for some help getting my lathe running again. It has a Fanuc 3T with DC servo's and spindle drive.
When starting up it gives an alarm of SERVO ALARM :01 (OVERLOAD) with a flashing NOT READY under that, the manual says that this alarm is an overload signal in X and Z.
There are no lights on on the spindle drive and both axis drives have the green RDY lights lit but the PRDY is off and no red lights.
Starting with P and CANCEL depressed does not help.
I checked the temp sensors on X and Z and both show closed.
The program I was running when this started has a lot of grooving so it would feed in then rapid back out and move in Z to the next cut and repeat, this program does this about 40 times.
A possible red herring is the motor was always decelerating when this happened and it did it once when initializing at start up when you have to do a gear change and it jogs the spindle.
Of course this happens on a hottish job and is the only lathe big enough to handle the material. Any help is appreciated.
