Fuling DZB200 Inverter

[Doddy]

Rather than playing with settings - following the logic that this was configured by OEM, it might be worthwhile investigating the behaviour of the VFD/motor with all settings as default. You can change the display on the VFD - currently showing the internal DC voltage, which is largely irrelevant, press the FUNC/DATA button until you display "n....." - that's the frequency of the output signal. Confirm that the rotary pot allows you to operate this away from zero. If it stays at zero, that's a big clue. If you can adjust it between 0 and (likely) 24000 and the motor doesn't turn, that's another (more sinister) clue.

Test and let us know.

Hi Doddy,

Thanks, I pressed the run button on the VFD then went to the "n" using func/data button the "run" led lights up but when I turn the pot it just stays at 0 and spindle doesn't run
