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

The GrFL parameter on the ATV630 drive stands for "Ground Fault Activation". It is used to configure the behavior of the SCF3 (Ground Fault Detection) function.

Parameter Options:
inH – Inhibits SCF3 detection
Yes – Activates "SCF3 detection" (default setting)
Percentage (%) – Sets a custom detection threshold based on the drive's nominal current

Default Behavior:
SCF3 is enabled by default (Yes)
The detection level is internally set to 25% of the drive's nominal current (In).

Custom Configuration:
To adjust the SCF3 detection level, set the GrFL parameter to a desired percentage.
Important: Ensure the access level is set to Expert mode before making changes.

Example:
If GrFL = 70%, the SCF3 detection threshold is set to 70% of the drive’s nominal current (In).
