5.16 Protection of parameters (Group PF)
PF.00 User password
Range: 0～9999【0】
Note:
◆User password setting: The initial value of user password is 0, which means the
password protection function is invalid. At this state, user can access all parameters
and parameters content of Group PF.
◆Unlock the user password: If the user password is effective, the preset password is
required to access Group PF. Otherwise, no parameters of Group PF can be accessed.
◆Changing the user password: If password protection function is effective, right
password must be input first to unlock. After unlocking, select PF.00, re-change this
parameter value, and press “ENTER” to save the value. Now, the password changing
is completed. Before changing the user password, remember to set PF.01 to 0, so that
all parameters are allowed to be changed.
 Tips:
The password will become effective when you press“PRG/ESC” to exit from Group PF
if you set user password.
Please remember the password; otherwise, you will have no access to all parameters of
Group PF.
If you forget user password, please contact with manufacturer,
Example: Set the password to 1234, then exit from Group PF and unlock the user
password. The process is shown in Fig. 5-15-1 and Fig. 5-15-2.
