cuit, main circuit and ground to
find out the source of interfer‐
ence
● Replace the frequency con‐
verter
Parameter initialization
Replace the operating panel
Should be solved during develop‐
ment
Replace the frequency converter
Check the input power supply
Increase the power capacity
Remove the input phase loss sit‐
uation
Replace the frequency converter
● Check the wiring
● If it fails again, contact with
technical service
