3. Either:
• Press the red reset button
• Toggle the reset digital input

Pr 10.38 to 100 (ensure that Pr. xx.00 returns to 0).
7.9 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 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 the table below:
RW = Read / write access RO = Read only access
The default settings of the drive are Parameter Access Level L1 and
user Security Open, i.e. read / write access to Menu 0 with the advanced
menus not visible.
7.9.1 Access Level
The access level is set in Pr 0.49 and allows or prevents access to the
advanced menu parameters.
7.9.2 Changing the Access Level
The Access Level is determined by the setting of Pr 0.49 as follows:
The Access Level can be changed through the keypad even if the User
Security has been set.
7.9.3 User Security
The User Security, when set, prevents write access to any of the
parameters (other than Pr. 0.49 and Pr 11.44 Access Level) in any
menu.
Setting User Security
Enter a value between 1 and 999 in Pr 0.34 and press the button;
the security code has now been set to this value. In order to activate the
security, the Access level must be set to Loc in Pr 0.49. When the drive
is reset, the security code will have been activated and the drive returns
to Access Level L1. The value of Pr 0.34 will return to 0 in order to hide
the security code. At this point, the only parameter that can be changed
by the user is the Access Level Pr 0.49.
Unlocking User Security
Select a read write parameter to be edited and press the button, the
upper display will now show 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 display will revert to
parameter view mode.
To lock the User Security again, set Pr 0.49 to Loc and press the
reset button.
