Password
Registering a 4-digit password can restrict access to parameters (reading/writing).
These parameters can be set when Pr.160 User group read selection = "0". However, when Pr.296 ≠ 9999 (password lock
is set), 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
selected with Pr.296 .
○ : Enabled, ×: Disabled
*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 in the initial setting) is restricted. (For the PU operation mode
command source selection, refer to
page 223 .)
*4 Access from the command source in the Network operation mode (the RS-485 communication or a communication option in the initial setting) is
restricted. (For the NET operation mode command source selection, refer to
page 223 .)
*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 are always
read/write enabled whether registered to a user group or not.
*6 If a communication option is installed, the Option fault (E.OPT) occurs, and the inverter output shuts off.
*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.
 Locking parameters with a password (Pr.296, Pr.297)
• The procedure of locking parameters with a password is as follows.
1.
Set the parameter reading/writing restriction level to enable the password protection. (Set a value other than "9999"
in
Pr.296 .)
Pr. Name Initial value Setting range Description

Password lock level 9999
0 to 6, 99, 100 to
106, 199
Password protection enabled. Setting the access
(reading/writing) restriction level to parameters locked
with a password enables writing to
Pr.297 .
