The PowerFlex 4 drives have a display that shows fault codes for these drives.  Common PowerFlex 4 Faults are below:

PowerFlex 4 F004 or F4 UnderVoltage:

This fault indicates Undervoltage, and specifically the DC bus voltage fell below the minimum value.  Possible action includes monitoring the incoming AC line power to determine if their is low voltage or interuption of incoming power. 

PowerFlex 4 F005 or F5 OverVoltage:

This fault indicates Overvoltage, and specifically the DC bus voltage has exceeded the maximum allowed value.  Possible action includes monitoring the incoming AC line power, another possible cause is the bus overvoltage could be caused by the regeneration from the motor due to it decelerating. 

PowerFlex 4 F007 or F7 Motor Overload :

The drive has had an internal electronic overload trip.  This can be caused when an excessive motor load is present, the user should also check parameter Boost Select which is A084. 

To Reset the PowerFlex 4 AC Drives to factory defaults:

The PowerFlex 4 drives can be reset to default settings by selecting Parameter P041 and then inputting the value of 1.  This will cause F048 or F48 indicating the params defaulted fault.
