Misoperation prevention and parameter setting restriction
<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 = any of "100 to 106, 199"], if password unlock error has occurred 5 times, correct password will not unlock
the restriction. (During password lock)
 Perform all parameter clear.
(3) Parameter operation during password lock/unlock
∗1 Reading/writing is unavailable when there is restriction to reading by the Pr. 160 setting. (Reading is available in NET mode regardless of Pr. 160 setting.)
∗2 Unavailable during the operation.
∗3 Correct password will not unlock the restriction.
∗4 Parameter clear is available only from the CC-Link communication option.
REMARKS
 After registering a password, a read value of Pr. 297 is always one of "0" to "5".
 When a password restricted parameter is read/written, is displayed.
 Even if a password is registered, parameters which the inverter itself writes, such as inverter parts life, are overwritten as
needed.
NOTE
 If the password has been forgotten, perform all parameter clear to unlock the parameter restriction. In that case,
other parameters are also cleared.
 Parameter all clear can not be performed during the operation.
 Do not use the FR Configurator when parameter read is restricted (Pr. 296 = any of "0, 4, 5, 99, 100, 104, 105, 199").
FR Configurator may not function properly.
REMARKS
 The password unlock method is different for operation panel and CC-Link communication.
