5.8 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 22) 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 5-7.

Table 5-7 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.

5.8.1 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

(00.010); these are shown in the

table below.

5.8.2 Changing the User Security Level /Access

Level

The security level is determined by the setting of Pr

or Pr

The Security Level can be changed through the keypad even if the User
Security Code has been set.

5.8.3 User Security Code

The User Security Code, when set, prevents write access to any of the
parameters in any menu.

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

. When the drive is reset, the security code will have been

activated and the drive returns to Menu 0. The value of Pr

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 display will now show ‘Co’. 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 ‘Co.Err’ is
displayed, and the display will revert to parameter view mode.

Disabling User Security

Unlock the previously set security code as detailed above. Set Pr

00.025

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.
