REMARKS
⋅When Pr. 296 = any of "4, 5, 104, 105" (password lock), the setting screen for PU JOG frequency is not displayed in the
parameter unit (FR-PU04/FR-PU07).
⋅During password lock, parameter copy of the operation panel (FR-DU07)/the parameter unit (FR-PU07) cannot be performed.
⋅Parameter settings in the inverter can be read/written using GX Developer even when the password function (Pr.296, Pr.297) is
valid. To use the password function and the PLC function at the same time, apply a lock to reading/writing of the ladder program
by registering a keyword.
