When I haven't used my 1642EVS recently it won't turn on. If I fiddle with the white knob on the inverter it will run again.
The display on the inverter goes up and down with the main speed control knob, and reads the same whether the lathe is on or not. Turning the knob on the inverter doesn't seem to change anything, nor does pushing the green and red buttons.
If anyone knows how this stuff works, I would greatly appreciate some help.
