Hallo Guys

My cnc router spindle suddenly just sopped responding when i turn it on from the control panel. The machine's other movements are okay. I know it must be a problem with VFD inverter or something technical. the spindle spins by hand and I can also change the tool manually.

My question is, How do I reset the VFD inverter or input new settings?

The inverter is a Chinese made "SJZO" model 511M... or something like that.

please help
