Is it possible to disable the SCF3 fault on ATV630 drive.

 On ATV630, there is a parameter named GrFL "ground fault activation".
 With this parameter, we can inhibit SCF3 (inH), activate it (Yes ) or set a percentage.
 By default: the SCF3 is activated (Yes) and the detection level is internally set to 25% of In Drive.
 The user can adjust the SCF3 level via this GrFL parameter; put the access level in Expert mode before.
 
Note: GrFL parameter is a value given in percent of Drive nominal current. For example: when GrFL = 70%, the SCF3 detection level is at 70% of In Drive.
