6.7.1 Data Protection Key
Data protection keys can inhibit data from being set or erased. There are three types of data
protection keys as shown below (the key names depend on the machine makers. For the details, refer
to the manuals issued by individual machine makers).
1) KEY 1: Protection of all tool data and coordinate system values preset by origin setting
2) KEY 2: Protection of user parameters and common variables
3) KEY 3: Protection of work programs
The data protection keys protect data when they are turned off.
