5.9 Parameter access level and security
The parameter access level determines whether the user has access to
Menu 0 only or to all the advanced menus (Menus 1 to 41) in addition to
Menu 0.
The User Security determines whether the access to the user is read
only or read write.
Both the User Security and Parameter Access Level can operate
independently of each other as shown in Table 5-8.
Table 5-8 Parameter access level and security
The default settings of the drive are Parameter Access Level Menu 0
and user Security Open i.e. read / write access to Menu 0 with the
advanced menus not visible.
