Password lock/unlock (Pr. 296, Pr. 297 )
<Lock>
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 a four-digit number (1000 to 9998) in Pr. 297 as a password.
(When Pr. 296 = "9999", Pr. 297 cannot be written.)
When the 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 also cleared.
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 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. (Refer to page 60)
 During password lock, parameter copy of the parameter unit (FR-PU07) cannot be performed.
