This is a fault in the current sensor. The unit must be uninstalled and returned for factory service.

Other codes that mandate a return for factory service are:
HPF.1 through HPF.4
cF3.3 through cF3.8

First thee attempts will "lock" you out. you must restart drive to allow 3 more tries. If you can't get to programming funcitons to change password you should be able to connect via serial connection and reset the password funcitons to 0. See attached pdf file for directions to connect pc to drive:

If you don't have your manual to expalin password functions you can also find it at:

A GFF error on most Vfd's refer to a in-proper ground, no ground detected , or a possible ground loop. Ground loops are a common mistake, where in the attempt the user grounds two or more devices or the load to the vfd as well as the mains ground.

the model your using is a three phase input, it can handle delta or wye, style of wiring, but all require a good ground source. If anything, just run a dedicated ground to each device and don't run ground wires to each other. It's only used for voltage reference between the phases. Without it, the vfd cannot work properly and will error.

why cant you use the keypad/'display of drive, is it not lit up ? if so you most likely have a grounded phase on the load side (motor) I suggest disconnecting motor completely and measuring to ground with a high voltage tester (megger) if you have a phase to ground then all the power that drive puts on that wire will shunt to ground , causing infinite current , this will affect the power supply of drive and not allow drive to even power up correctly
also you failed to mention if motor was 3 phase if so , some drives require installer to remove shunt jumpers (see install directions) this will "Lift" the surge suppresors off earth ground and over to "virtual" ground that occurs at center of three phase power , this might be seen as a ground fault if this is not done correctly

You can search it in Google or Alibaba to find its store. Besides, Veichi Electric is a good alternative to Delta. Veichi Electric provides various kinds of VFDs such as air compressor inverter, injection molding machine inverter, mini inverter and more.
