Password - Mitsubishi Electric FR-A800 Series Instruction Manual

5.7.14 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.

*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.
 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.296 setting
0 to 6 or 99
*1
100 to 106, 199
*1 If an invalid password is input 5 times while any of "100 to 106, or 199" is set in Pr.296, the password is locked up afterward (the locked parameters
cannot be unlocked even with the valid password). All parameter clear is required to reset the password. (After All parameter clear is performed,
the parameters are returned to their initial values.)
