How to solve the problem that the inverter power supply is not displayed? Today, I will introduce to you the solution.
Problem : FULING inverter don’t power showing ,other parts power normal
 
Machine Detail: AKM6012  Mach3 system

Related reasons:
1) Measure really input voltage by multimeter and check machine voltage .
2) Check inverter input power wire if loose  

Solution: measure input power voltage is 122.4V , because machine input voltage is 1Phase 220V , so input voltage is wrong . change right voltage . it is ok .
