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.
