Communication E²Prom Write Selection (Pr. 342) - Mitsubishi Electric FR-E700 Instruction Manual

Communication operation and setting
6.19.3 Communication E²PROM write selection (Pr. 342)
When parameter write is performed from the inverter PU connector, USB communication, and
communication option, parameters storage device can be changed from E²PROM + RAM to
RAM only. Set when a frequent parameter change is necessary.
When changing the parameter values frequently, set "1" in Pr. 342 to write them to the RAM on-
ly. The life of the E²PROM will be shorter if parameter write is performed frequently with the set-
ting unchanged from "0 (initial value)" (E²PROM write).

E²PROM write selection
The above parameter can be set when Pr. 160 "User group read selection" = 0. However, the
parameter can be set whenever the communication option is connected. (Refer to
section 6.17.4).
NOTE When "1" (write to RAM only) is set in Pr. 342, powering off the inverter will erase the
changed parameter values. Therefore, the parameter values available when power is
switched on again are the values stored in E²PROM previously.
