1) Set parameter reading/writing restriction level. (Pr. 296 9999)
Pr.296 Setting
Restriction of Password
Value
1 to 6
101 to 106
* During [Pr. 296 = "101 to 106"], if password unlock error has occurred 5 times, correct password will not unlock the
restriction. All parameter clear can unlock the restriction.
(In this case, parameter settings are cleared.)
2) Write four-digit numbers (1000 to 9998) in Pr. 297 as a password.
(When Pr. 296 = "9999", Pr. 297 cannot be written.)
When password is registered, parameter reading/writing is restricted with the restriction set level in Pr. 296 until
unlocking.
REMARKS
After registering a password, a read value of Pr. 297 is always "0" to "5".
When a password restricted parameter is read/written, "
Even if a password is registered, parameters which the inverter itself writes, such as inverter parts life, are overwritten as
needed.
Even if a password is registered, Pr. 991 PU contrast adjustment can be read/written when a parameter unit (FR-PU04/FR-PU07)
is connected.
<Unlock>
There are two ways of unlocking the password.
Enter a password in Pr. 297.
Unlocked when a password is correct. If a password is incorrect, an error occurs and not unlocked.
During [Pr. 296 = "101 to 106"], if password unlock error has occurred 5 times, correct password will not unlock the
restriction. (During password lock)
Perform All parameter clear.
Password lock is unlocked. However, other parameter settings are cleared also.
NOTE
If the password has been forgotten, perform All parameter clear to unlock the parameter restriction. In that case,
other parameters are also cleared.
All parameter clear cannot be performed during the operation.
Do not use the FR Configurator under the conditions that parameter read is restricted (Pr. 296 = "4, 5, 104, 105").
FR Configurator may not function properly.

REMARKS
When Pr. 296 = "4, 5, 104, 105" and using the parameter unit (FR-PU04/FR-PU07), PUJOG operation is unavailable.
When writing is restricted from PU mode operation command (Pr. 296 = 1, 2, 4, 5, 101, 102, 104, 105), switching of operation
mode by easy setting mode is unavailable.
During password lock, parameter copy of the parameter unit (FR-PU07) cannot be performed.
