Password

Registering a 4-digit password can restrict access to parameters (reading/writing).
Pr.
296
Password lock level
E410
297
Password lock/unlock
E411
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.

Only the parameters registered in the user group can be read/written. (For the parameters not registered in the user
99, 199
group, the restriction level when "4 or 104" is set applies.)
○: 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
*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
*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.)
