spindle motor overload
I have a 3 axis cnc kneemill (FV-1) running off a 3 phase rotary convertor that keeps tripping the spindle motor controller overload. unfortunately I do not have access to a clamp meter. Is there any other way I can check to see why it may be tripping? I have checked all the connections from the motor to the controller and they seemed fine.
The overload trips at odd times sometimes when I stop the spindle (There is no spindle brake), as it's running, and I've even had it trip a couple times just sitting there idle (Spindle off and me elsewhere). Could this be due to my phase convertor somehow?
Thanks
Brian
