So my spindle stopped during milling last night. It had been running for 2 hour straight.
Both the spindle and the VFD is new from China.
I couldnt feel any heat from the spindle, or abnormal smell from either the VFD or the spindle.
The VFD shows Error 4 which I understand is a normal error on these VFD's
The error shows when I press Run on the VFD panel. The error will also show if the VFD and the pindle is disconnected and I press run.
I measure 2.9ohms between all the spindle pins except for ground.
Anyone have an Idea of what I should do next?
Is the spindle probably ok?
