Fanuc 0iMC -9031 Motor lock or V Sig Loss
Dear Sirs
In MDI/Auto mode, only in case of one particular tool, when spindle speed is more than 1500 rpm, we find Load on spindle (L) as seen at the bottom of position screen to be shooting upto 164%(although tool is running on load ie not in touch with job) and hence trips with alarm 9031, we dont have this problem in case of any other tools even at 2000 rpm
We replaced tool with new one
Spindle Motor has timing belt and there is no gear box.
We can not doubt feedback, as no problem in case of any other tools even bigger than this one
With same set of toolings and same job being made since last 5 years
Kindly revert

Does the motor have dual winding contactor? It may be one 'range' contacts are bad.

I would check the pullstud first, if it is different, it may lead to different travel of the collet mechanism
