Problems With Variable Frequency Power Supply

[Chessie]

I have an Industrian Hobbies mill with a company installed T-Verter N2 Series variable frequency motor control that had been operating fine until this past weekend. Now when I go to turn on the motor, I get and error message that reads "Err1" and nothing happens. Nothing has changed with the installation or wiring. Has anyone run into this before, and how do I fix this?

Page 64 of the manual provides a list of checks to make to clear the error code. I do not own this VFD, but I found the manual with a quick google search. Hope this helps.
