Registering 4-digit password can restrict parameter reading/writing.

∗2
Password lock/unlock
The above parameters allow their settings to be changed during operation in any operation mode even if "0 (initial value) or 1" is set in Pr. 77 Parameter
write selection.
∗1
This parameter can be set when Pr. 160 User group read selection = "0."
∗2
If Pr. 296 = "9999" (no password lock), Pr. 297 can be set while Pr. 160 = "0." When the password lock is valid, Pr. 297 can be set regardless of the Pr. 160
setting.
∗3
Pr. 297 can be written as "0 or 9999," but the Pr. 297 setting does not change.
.............. Specifications differ according to the date assembled. Refer to page 338 to check the SERIAL number.

(For the parameters not registered in the user group, same restriction level as "4, 104" applies.)
∗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 205
for PU mode operation command source selection)
∗4
This restricts parameter access from the command source that can write a parameter under Network operation mode (initially RS-485 communication from
PU connector or a communication option). (Refer to page 205 for NET mode command source.)
∗5
Read/write is enabled only in the simple mode parameters registered in the user group when Pr.160 User group read selection = "9999". Pr.296 and Pr.297 are
always read/write enabled whether registered to a user group or not.
∗6
If a communication option is installed, option fault (E.OPT) occurs, and inverter trips. (Refer to page 299.)
