Denial of parameter change

What does F01659 mean?

This fault occurs when the drive rejects a write request for one or more safety parameters, often due to problems finalizing parameters, an incorrect safety password, or an insufficient tolerance setting (p9691/p9891 too small). The drive may revert to previous settings, indicating an issue with security or parameter validation within the safety configuration.
