Password Function/Registering A 4-Digit Password Can Restrict Parameter Reading/Writing; Parameter Reading/Writing Restriction Level (Pr.296); Registering A Password (Pr.296, Pr.297) - Mitsubishi Electric FR-F800 Instruction Manual

Password function
Registering a 4-digit password can restrict parameter reading/writing.

The above parameters can be set when Pr.160 User group read selection = "0". However, whenPr.296(password lock is set),Pr.297can always be set,
regardless of the setting inPr.160

When Pr.297 = "0, 9999", writing is always enabled, but setting is disabled. (The display cannot be changed.)
Parameter reading/writing restriction level (Pr.296)
• The level of the reading/writing restriction using the PU/Network (NET) operation mode operation command can be
selected with Pr.296.

(For the parameters not registered in the user group, same restriction level as "4, 104" applies.)

If the parameter reading is restricted by the Pr.160 User group read selection setting, those parameters are unavailable for reading even when

If the parameter writing is restricted by the Pr.77 Parameter write selection setting, those parameters are unavailable for writing even when


This restricts parameter access from the command source that can write a parameter under the PU operation mode (initially the operation panel
(FR-DU08) or the parameter unit). (For the PU operation mode command source selection, refer to

This restricts parameter access from the command source that can write a parameter under the Network operation mode (initially the RS-485
terminals or a communication option). (For the NET operation mode command source selection, refer to

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.

If a communication option is installed, an option fault Option fault (E.OPT) occurs, and the inverter output shuts off. (Refer to

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.
Registering a password (Pr.296, Pr.297)
• The following section describes how to register a password.
1)Set the parameter reading/writing restriction level. (Pr.296  "9999")
Pr.296 setting
0 to 6, 99 No restriction
100 to 106, 199 Restricted at fifth error


During Pr.296 = any of "100 to 106, 199", if password unlock error has occurred 5 times, correct password will not unlock the restriction. All
parameter clear can unlock the restriction. (In this case, the parameters are returned to their initial values.)
2)Write a four-digit number (1000 to 9998) in Pr.297 as a password. (Writing is disabled when Pr.296="9999".) When a
password is registered, parameter reading/writing is restricted with the restriction level set in Pr.296 until unlocking.
