(For the parameters not registered in the user group, same restriction level as "4, 104" applies.)
Tab.6-52: 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, parameter unit) is restricted. (Refer to section 6.18.3 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 RS-485 communication from PU connector or a communicati-
on 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).
