be read.)
To register a parameter to the user group, set its
parameter number in [Pr. 173]. To delete a parameter
in the user group, set its parameter number in [Pr.
174] . Set [Pr. 172 = 9999] to batch delete parameters
registered.

[Pr. 77, Pr. 160 and Pr. 991] can always be read,
independently of the user group setting.
[Pr. 77, Pr. 160, Pr. 172 to Pr. 174] cannot be registered
to the user group.
When [Pr. 173, Pr. 174] is read, 9999 is always
displayed.
When any value other than 9999 is set in [Pr. 172], no
function is available.

writing when a password is registered.
9999 No password lock
1000 to 9998 Register a 4-digit password
Displays password unlock error count. (Reading

(2) Password lock/unlock [Pr.296, Pr.297]
1) Lock
Set parameter reading/writing restriction level by
Pr. 296. ([Pr. 296 ≠ 9999])
When the setting is "101 to 106", the number of
password unlock errors (0 to 5 times) is displayed
when [Pr. 297] is read.
(When the [Pr. 296] setting is "1 to 6", the number
is not displayed.
Write four-digit number (1000 to 9998) in [Pr.297]
as a password.
(When [Pr. 296 ="9999"], Pr.297 cannot be written.)
Once password is registered, parameter reading/
writing is restricted with the restriction level set in
[Pr. 296] until password unlock.
After registering a password, a read value of [Pr.
297] is always "0" to "5". When a password
restricted parameter is read/written,
displayed. Even if a password is registered,
parameters which the inverter itself writes, such
as inverter parts life, are overwritten occasionally.
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.
