Appendix 4.1 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 manufacturers. For the details, refer to the manuals
issued by individual machine manufacturers).
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.
