Hello,
When powering up and running the spindle for about 30s, its runs so very hot that you cant keep you hand over the spindle for a couple seconds! The spindle is rated for 8A and the VFD is rate at 10A. There is something I dont have correct as it seems the spindle is being electrically overloaded!
I have gone through 2 VFDs now thinking that my VFD was defective but I get the same result so its definitely something I am doing wrong!
VFD Info
I have attached the VFD manual but it can also be seen online.
