Only parameters registered in the user group can be read/written.

(For the parameters not registered in the user group, same restriction level as "4, 104" applies.)
Tab. 6-41: Level of password lock and reading/writing restriction
If the parameter reading is restricted by the Pr. 160 setting, those parameters are unavailable
for reading even when "✔" is indicated.
If the parameter writing is restricted by the Pr. 77 setting, those parameters are unavailable
for writing even when "✔" is indicated.
Parameter access from unit where parameter is written in PU operation mode (initially set
to operation panel (FR-DU07), parameter unit) is restricted. (Refer to section 6.17.3 for PU
mode operation command source selection.)
This restricts parameter access from the command source that can write a parameter under
Network operation mode (initially RS485 terminal or a communication option).
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.
If a communication option is installed, option fault (E.OPT) occurs, and inverter trips (refer
to section 7.2).
