5.4.13 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
≠
9999 (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.
If the parameter reading is restricted by the Pr. 160 "User group read selection" setting, those
parameters are unavailable for reading even when "
 " is indicated.
If the parameter writing is restricted by the Pr. 77 "Parameter write selection" setting, those
parameters are unavailable for writing even when "
 " is indicated.
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 page 5-130.)
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 page 5-130.)
!
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.
