Note
Software versions V03.01.07 onward allow
the advanced parameters to be read and

irrespective of the security state.
B.1 User-defined Security
The Drive is supplied without User Security having
been set-up. All parameters can be read and all
read–write parameters can be edited.
User-defined Security operates only when it has
been set-up by the user. When locked, it prevents
editing of all parameters except for parameter
0.00.
The code number used to unlock User-defined
Security is defined by the user. This gives
protection against unauthorized editing of
parameters. The code number can be read and
edited only when User Security has been unlocked.
B.2 Setting-up User Security
Set-up User Security as follows:
1. Select parameter 0.34 User security code. The
default value 149 is displayed.
2. Change the value to the required User Security
number which must be within the range 0 to
255. Do not use the default value 149.
3. When the display is returned to Parameter
mode, the displayed value reverts to 149. This
hides the new User Security number.
4. Follow the procedure in Saving new
parameter-values in Appendix A Programming
Instructions.
User Security is now set-up.
B.3 Unlocking User Security
When User Security has been set-up and AC power is
applied to the Drive, User Security is automatically
locked. No parameters can be edited except for
parameter .00 in any menu.
Unlock User Security as follows:
1. Select parameter 0.00.
2. Set the value at the User Security code number.
All read–write parameters can now be edited.
B.4 Locking User Security
When User security has been set up, and the
AC supply is removed and subsequently re-applied,
User security becomes locked.
To lock User security without removing the
AC supply, set parameter 0.00 at 2000.
