5.4 Security and parameter access
The navigation buttons can only be used to move between menus and parameters if the parameter access level User Security Status ( H02 ) has been
set to show 'All Menus'. The security and parameter access level determines whether the user has access to User Menu A only, or to all menus in
addition to User Menu A. The security also determines whether the user has read only (RO) or read write (RW) access. The
E300 Advanced Elevator
drive provides a number of different levels of security that can be set by the user via User Security Status ( H02 ) as shown in Table 5-6.
Table 5-6 Security and parameter access
The default security and parameter access levels for the drive are,
•
Parameter access level = User Menu A
• Security = Open i.e. read / write access to User Menu A with the all menus not visible.
Both the security and parameter access level can operate independently of each other as shown in Table 5-7 Security, Parameter access level
Table 5-7 Security, Parameter access level
5.5 Changing security and parameter access
The security level is determined by the setting of User Security Status ( H02 ). The security level can be changed through the keypad even if a security
code has been set. The security code, when set, prevents write access to any of the parameters in any menu.
5.5.1 Setting security code
Enter a security code value between 1 and 2147483647 in User Security Code ( H01 ) and press the button; the security code has now been
set to this value.
5.5.2 Setting parameter access level
To activate the security, the parameter access level must be set to the desired level in User Security Status ( H02 ). When the drive is reset, the
security code will have been activated and the drive returns to User Menu A and the symbol is displayed in the right hand corner of the keypad
display. The value of User Security Code ( H01 ) will return to 0 in order to hide the security code.
5.5.3 Unlocking security code
Select a parameter that needs to be edited and press the button, the upper display will now show ‘Security Code’. Use the arrow buttons to
set the security code and press the button. With the correct security code entered, the keypad display will revert to the parameter selected in
edit mode. If an incorrect security code is entered, the following message ‘Incorrect security code’ is displayed, then the display will revert to
parameter view mode.
5.5.4 Disabling security
To unlock the previously set security code as detailed above. Set User Security Code ( H01 ) to 0 and press the button. The security has now
been disabled, and will not have to be unlocked each time the drive is powered up to allow read / write access to the parameters.

Disabling security can lead to parameter values being changed without careful consideration; ensure a security code is active to avoid
incorrect or unintentional parameter adjustments which could lead to damage or a safety hazard.
