G'day all,
I had a chance to plug in my 4kw Huagyang VFD and spindle, however it plays havoc with my volt/amp gauge.
You can see, after a couple of seconds, volt and amp goes all over the place. I have used shield VFD cable and shielded both end to AC earth. In the control box, AC earth is connected to DC low. I have disconnect it DC low and earth with no change. There is no interference any of the motors or drives. Any help would be appreciated.
Cheers Wayne.
