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.



Pr.297 can be written as "0 or 9999," but the Pr.297 setting does not change.

Parameter reading/writing restriction level (Pr.296 )

 Level of reading/writing restriction by PU/NET mode operation command can be selected by Pr.296.

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 page

195 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 communication option). (Refer to page 195 for NET mode command source.)



If a communication option is installed, option fault (E.OPT) occurs, and drive unit trips. (Refer to page 275.)
