Password Function - Mitsubishi Electric FR-A820-00046 Instruction Manual

Parameters
5.7.13

Password function

Registering a 4-digit password can restrict parameter reading/writing.
Pr.
296
E410
297
E411
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.

Tab. 5-79:
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 page 5-282.)
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 5-282.)
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.
