Misoperation prevention and parameter setting restriction
(2) Password lock/unlock (Pr.296, Pr.297 )
<Lock>
1) Set parameter reading/writing restriction level. (Pr.296  9999)
Pr.296 Setting
Value
0 to 6
100 to 106
 During [Pr.296 = any of "100 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 password is registered, parameter reading/writing is restricted with the restriction level set in Pr.296 until
unlocking.
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,
 Even if a password is registered, parameters which the drive unit itself writes, such as drive unit 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-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 = any of "100 to 106"], if password unlock error has occurred 5 times, correct password will not unlock the
restriction. (During password lock)
 Perform all parameter clear.
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.
REMARKS
 The password unlock method is different for operation panel/FR-PU07, RS-485 communication, and communication option.
All parameter clear
Parameter clear
 For parameter clear and all parameter clear from the communication option or the parameter unit (FR-PU07), refer to the
instruction manual of each options. (Refer to page 261 for the operation panel, refer to page 209 for the Mitsubishi inverter protocol
with RS-485 terminal communication, and refer to page 222 for Modbus-RTU communication protocol.)
