i find i have the same problem..i have disconnected every cable apart from the 240v input and it still comes up with e30.1 does this mean the vfd is toast or maybe the rfi filter thats inline just before it
any help appreciated

its a hitachi wj200 it has been working fine with a 24000 rpm chinese 2.2kw spindle . then the error came up . as said i plug everything apart from power in and it still has the error code
You will have to clear the fault, follow the manual on how to do this,\
To get this fault, you may not have set the correct Parameters in the VFD that suit your spindle, this is the normal cause of problems like this, wiring also can cause this problem
Have you checked the spindle Ground / Earth connection, Pin #4 has to be connected to the spindle most are not and need to be corrected
