If
Load Defaults
(11.043) is non-zero and a drive reset is initiated then the drive will load and save default parameters. If
Load Defaults
(11.043) = 1
then 50Hz defaults are loaded and if
Load Defaults
(11.043) = 2 then 60Hz 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 the it is cleared along with
Parameter mm.000
(mm.000) and
Parameter Cloning
(11.042) when the action is completed.

Security
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 in the table
below.

When security has been set up the drive can either be in the locked or unlocked state. In the locked state the security level that has been set up applies.
In the unlocked state the security is not active, 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 with the
User Security Status
(11.044) and initiating a drive reset.
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). For security to remain set after power
down then a parameter save should be performed to retain the set value.
2. If no further action is taken when the drive is powered down and then powered up read-only security will be set up and locked.
3. If at any time the
User Security Status
(11.044) is set to a value corresponding the one of the security levels shown in the table above
and a drive reset is performed the security level is changed to that level. The desired security level is automatically saved and retained
after power down, the keypad state changes to status mode and security is locked. (The security level that is active, provided
User Security Code
(11.030) has been saved as a non-zero value, if 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 any level of security is active and locked.
Security can be unlocked as follows:
1. If read-only security is set and locked then any attempt to 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 security is set and locked then any attempt to leave status mode causes the security code to be requested
as per the process described above. If 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:
