If LoadDefaults (11.043) is non-zero and a drive reset (or exit from edit in menu 0) is initiated then the drive will load and save default parameters. If
LoadDefaults (11.043) = 1 then standard defaults are loaded and if LoadDefaults (11.043) = 2 then US defaults are loaded. This parameter has priority
over actions defined by Parametermm.000(mm.000) and ParameterCloning (11.042). If LoadDefaults (11.043) is used to initiate loading defaults then
it is cleared along with Parameter mm.00 and ParameterCloning (11.042) when the action is completed.

Security
The drive provides a number of different access levels that can be set by the user via UserSecurityStatus (11.044) ; these are shown in the table
below.

The keypad remains in status mode and no parameters can be viewed or edited. Drive parameters cannot be
accessed via a comms/fieldbus interface in the drive or any option module.

In addition to these access levels, a security code can be used to provide further restriction. When a security code has been set up the drive can either
be in the locked or unlocked state. In the locked state the access level that has been set up applies and the security code will need to be entered to
change the access level or edit any parameters in the current access level. In the unlocked state the access level can be changed and parameters
edited, but when the drive is powered down and powered up again the drive will be in the locked state. The drive may be relocked without powering
down by selecting the required security level in Parameter 10 and pressing Enter.
Security can be set up as follows:
1. The UserSecurityCode (11.030) should be set to the desired security unlock code (not zero).
2. Select the required access level in Parameter 10 and press enter.
3. The desired access level is automatically saved and retained after power down, the keypad state changes to status mode and security
is locked if it has been setup. The access level that is saved is shown in SecurityStatus (11.085)
When security is set up and locked:
1. Parameter access is restricted as shown in the table above.
2. UserSecurityCode (11.030) reads as zero except in parameter edit mode. Therefore it is not possible to read the value of the security
code when security is active and locked.
Security can be unlocked as follows:
1. Any attempt to change access level using Parameter 10 or edit any read/write parameter causes "Security code" to be displayed on the
first row of the display. When the Up or Down keys are pressed the second row shows the code being adjusted. On setting the code the
user presses the Enter key. If the correct code has been entered then the drive switches to Parameter edit mode on the parameter the
user selected to edit, but if the correct code has not been entered the notification "Incorrect security code" is displayed for 2s and the
drive returns to Parameter view mode.
2. If Status only or No access has been set and locked then any attempt to leave status mode causes the security code to be requested
as per the process described above. The security code entered must be correct for the keypad state machine to switch to the
Parameter view mode. It is then possible to access all parameters normally.
Security can be cleared as follows:
1. Security must be unlocked.
2. The UserSecurityCode (11.030) should be set to zero. For security to remain cleared after power down then a parameter save should
be performed or Parameter 10 should be set to the required access level as with setting security.
