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

Registering 4-digit password can restrict parameter reading/writing.
(1) Parameter reading/writing restriction level
[
Pr. 296

Level of reading/writing restriction by PU/NET mode
operation command can be selected by [
Pr. 296
].
*1
If the parameter reading is restricted by the [
Pr. 160
]
setting, those parameters are unavailable for reading
even when "
{
" is indicated.
*2
If the parameter writing is restricted by the [
Pr. 77
] setting,
those parameters are unavailable for writing even when
"
{
" is indicated.
*3
Parameter access from unit where parameter is written in
PU operation mode (initially set to operation panel,
parameter unit) is restricted. (
Refer to page 436
for PU
mode operation command source selection)
*4
Parameter access in NET operation mode with RS-485
communication is restricted.
(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,
is
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
