Braking Resistors getting Super hot even with no Motors running

[Bryan Rogers]

Have A Chevalier Lathe that the Braking Resistors are getting super hot and smoking right after you turn on Machine,, You don't have to run the spindle.

Could there be a problem in the VFD braking circuit?

That's what it sounds like to me. Never heard of that before, but sounds like the brake chopper transistor is shorted.

That's what it was. Had it repaired along with the Braking Unit . Thanks
