These parameters can be set when Pr.160 User group read selection = "0". However, when Pr.296 ≠ 9999 (Password
protection enabled), Pr.297 can always be set, regardless of the setting in Pr.160.
*1 Although "0 or 9999" can be input in Pr.297, the value is invalid. (The display cannot be changed.)
 Parameter reading/writing restriction level (Pr.296)
• The access (reading/writing) restriction level to parameters in the PU operation mode or NET operation mode can be

*1 If the parameter reading is restricted by the setting of Pr.160 User group read selection, those parameters cannot be read even when "○" is
indicated.
*2 If the parameter writing is restricted by the setting of Pr.77 Parameter write selection, those parameters cannot be written even when "○" is
indicated.
*3 Access from the command source in the PU operation mode (the operation panel (FR-DU08) or the parameter unit in the initial setting) is
restricted. (For the PU operation mode command source selection, refer to
*4 Access from the command source in the Network operation mode (the RS-485 terminals or a communication option in the initial setting) is
restricted. (For the NET operation mode command source selection, refer to
*5 Read/write is enabled only for the simple mode parameters registered in the user group when Pr.160 = "9999". Pr.296 and Pr.297 can be read
or written regardless of whether they are registered to the user group.
*6 If a communication option is installed, the Option fault (E.OPT) occurs, and the inverter output shuts off. (Refer to
*7 The PLC function user parameters (Pr.1150 to Pr.1199) can be written and read by the PLC function regardless of the Pr.296 setting.
