*2*4
*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
"0 or 9999" can be set to Pr.297 at any time although the setting is invalid (the displayed value does not change).
*4
This parameter allows its setting 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) Parameter reading/writing restriction level (Pr. 296 )
Level of reading/writing restriction by PU/Network(NET) mode operation command can be selected by Pr. 296.

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 page 219 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 terminal or
a communication option). (Refer to page 219 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.
