True or False: Restoring an image backup erases F-ROM and SRAM files on the controller.

The statement is true because restoring an image backup typically involves replacing the current system state with a previously saved state. During this process, F-ROM (Firmware Read-Only Memory) and SRAM (Static Random Access Memory) files are often overwritten or erased to ensure that the controller returns to the exact condition that was captured in the backup.

When an image backup is restored, the control system's operational data and configurations that are retained in both F-ROM and SRAM are reset to the state defined by the backup. This means that any changes made after the backup was created will be lost, emphasizing the need for careful planning before restoring an image backup.

Understanding this concept is crucial for managing CNC systems effectively, as it ensures that operators are aware of the consequences and implications of restoring backups, particularly in relation to system settings and data integrity.
