4.17.5 Password function (Pr. 296, Pr. 297)
The above parameters can be set when Pr. 160 User group read selection = "0".
When Pr. 296
≠
"9999" (with password lock), note that Pr. 297 is always available for setting regardless of Pr. 160 setting.
*1 "0 or 9999" can be set to
Pr. 297
at any time although the setting is invalid (the displayed value does not change).
*2 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

Specifications differ according to the date assembled. Refer to page 399 to check the SERIAL number.
(1) Parameter reading/writing restriction level ( Pr. 296 )
Level of reading/writing restriction by PU/NET mode operation command can be selected by Pr. 296 .
*1 If the parameter reading is restricted by the Pr. 160 setting, those parameters are unavailable for reading even when " " is indicated.
*2 If the parameter writing is restricted by the Pr. 77 setting, those parameters are unavailable for writing even when " " is indicated.
*3 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 206 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 206 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.
*6 If a communication option is installed, option fault (E.OPT) occurs, and inverter trips. ( Refer to page 342 .)
Registering 4-digit password can restrict parameter reading/writing.
