The frequency inverter PF.00 shows 0000 means that someone has set password protection. Please check the following solutions.

1. If you know the password of the inverter, please just input it. Then set PF0.01 to 0 & set PF0.02 to 2 to restore defaults.

2. If you do not know the password, please enter into -PH- group as follow to cancel the password protection.
a. Please enter into -PF-
b. Press ">>" and “Enter” button together for more than 15 seconds. Then you can find -PH- group.
c. Press "Enter", then you can find "0000" showed in the display. Please input "8222" to replace "0000" & press "Enter", then you can find "PH.00" showed in the display.
d. Change PH.00 to PH.15 & set PH.15 to 1 & press "Enter", then the frequency inverter password protection is cancelled.
e. Set PF0.01 to 0 & set PF0.02 to 2 to restore defaults.
