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.
PF.01 Parameter write-in protection

0: All parameters are allowed changing;
1: Only setting frequency (P0.00) and PF.01 can be changed;
2: Only PF.01 can be changed.
Note:
◆
PF.01 is set to 0: All parameters are allowed to be changed But only the parameters,
which are marked “
○
” in function table, can be changed no matter what the ac drive is
running or not. The parameters, which are marked “×”can be only changed when the
ac drive is in stop state. Other parameters cannot be changed. About the changeable of
parameters, refer to Chapter 4 for details. In addition, you can examine the parameters
display on keyboard. If any digit of the parameter is flashing, the parameter is allowed
to change. If none digit of the parameter is flashing, it cannot be changed.
◆
PF.01 is set to 1: Only P0.00 and PF.01 can be changed;
◆
PF.01 is set to 2: only PF.01 can be changed.
Tips:
If PF.01 is set to 0 (all parameters are allowed changing), reference frequency, speed
PID input, and analog PID digital input can be adjusted and saved online in parameters
monitoring status.
If PF.01 is set to 1, only reference frequency can be adjusted online.
If PF.01 is set to 2, All online adjusting are disabled.
PF.02 Parameter initialization

0: No operation
1: Clear fault history
2: Restore to defaults (except records and password).
Note:
◆
PF.02 is set to 0: No operation.
◆
PF.02 is set to 1: When PF.02 is set to 1, the fault records of PE.00~PE.08 will be
cleared in favor of faults debugging and analyzing.
◆
PF.02 is set to 2: If PF.02 is set to 2, the parameters (except running history and user
password) are restored to defaults.
Tips:
If user forget the setting value of parameters, and do not want to set them one by one,
setting PF.02 to 2 can be used to rapidly restored to defaults, in favor of parameters
resetting.
PF.02 will be restored to 0 automatically after clearing the fault records or restoring to
