Parameter Reading/Writing Restriction When The Password Function Is Active - Mitsubishi Electric 800 Series Instruction Manual

4.7 Parameter reading/writing restriction when the password
function is active
• When a password is registered, parameter reading/writing via the RS-485 terminals is restricted as follows according to the
setting in Pr.296 Password lock level.
Pr.296 setting

Only the parameters registered in the user group can be read/written.
99, 199 (For the parameters not registered in the user group, same restriction level as
"4, 104" applies.)

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 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.
NOTE
• When all parameter clear is performed during communication via the RS-485 terminals, the set password is cancelled.
(The password is not cancelled by performing parameter clear.)
• For the details of the password function, refer to the Instruction Manual (Detailed) of the inverter.
