Parameter Misoperation prevention and parameter setting restriction

Password lock/unlock (Pr. 296, Pr. 297)
●
Lock
햲
Set parameter reading/writing restriction level (Pr. 296 9999).
During Pr. 296 setting of any of "100 to 106 or 199", 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.)
햳
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.

NOTES 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, "LOCd" is displayed.
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.
