Table 5-10 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.
5.9.1 User Security Level / Access Level
The drive provides a number of different levels of security that can be set
by the user via
User Security Status (11.044); these are shown below.
5.9.2 Changing the User Security Level /Access
Level
The security level is determined by the setting of Pr 00.049 or Pr 11.044 .
The Security Level can be changed through the KI-Remote Keypad even
if the User Security Code has been set.
5.9.3 User Security Code
The User Security Code, when set, prevents write access to any of the
parameters in any menu.
Setting User Security Code
Enter a value between 1 and 2147483647 in Pr 00.034 and press the
button; the security code has now been set to this value. In order
to activate the security, the Security level must be set to desired level in
Pr
00.049 . When the drive is reset, the security code will have been
activated and the drive returns to Menu 0 and the symbol is
displayed in the right hand corner of the keypad display. The value of
Pr
00.034 will return to 0 in order to hide the security code.
Unlocking User Security Code
Select a parameter that need 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 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.
Disabling User Security
Unlock the previously set security code as detailed above. Set Pr 00.034
to 0 and press the button. The User 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.
