PARAMETERS
NOTE
• After registering a password, the read value of Pr.297 is always one of "0 to 5".
• appears when a password restricted parameter is read/written.
• Even if a password is registered, the parameters, which the inverter itself writes, such as inverter parts life are overwritten as
needed.
• Even if a password is registered, reading/writing is enabled for Pr.991 PU contrast adjustment when the parameter unit
(FR-PU07) is connected.
Unlocking a password (Pr.296, Pr.297)
• There are two ways of unlocking the password.
• Enter the password in Pr.297. If the password matches, it unlocks. If the password does not match, an error occurs and the
password does not unlock. When any of "100 to 106, or 199" is set in Pr.296 and a password unlock error occurs five times,
the restriction will not be unlocked even if the correct password is subsequently input. (Password lock in operation.)
• Perform all parameter clear.
NOTE
• If the password is forgotten, it can be unlocked with all parameter clear, but doing so will also clear the other parameters.
• All parameter clear cannot be performed during the operation.
• During the conditions where parameter reading is disabled (Pr.296 = any of "0, 4, 5, 99, 100, 104, 105, or 199"), do not use
FR Configurator2. It may not operate correctly.
• The password unlocking method differs between the operation panel, parameter unit, RS-485 communication, and
communication option.
: Password can be unlocked, : Password cannot be unlocked
• For the parameter clear and parameter all clear methods for the communication option and parameter unit, refer to the
Instruction Manual of each option. (For the operation panel (FR-DU08), refer to page 631, for the Mitsubishi inverter protocol
of RS-485 communication, refer to page 565, and for the Modbus-RTU communication protocol, refer to page 579.)
Parameter operations during password locking/unlocking
: Enabled, : Disabled
 Reading/writing is disabled if reading is restricted by the Pr.160 setting. (Reading is available in the Network operation mode regardless of the
Pr.160 setting.)
 All parameter clear cannot be performed during the operation.
 Correct password will not unlock the restriction.
 Parameter clear can only be performed from the communication option.
NOTE
• When Pr.296 = "4, 5, 104, or 105" (password lock), the setting screen for PU JOG frequency is not displayed in the parameter
unit (FR-PU07).
• When the password is being locked, parameter copy using the operation panel, parameter unit, and USB memory is not
enabled.
