Communication Eeprom Write Selection (Pr. 342) - Mitsubishi Electric FR-A7NP E kit-SC Instruction Manual

INVERTER SETTING
4.3.1

Communication EEPROM write selection (Pr. 342)

When parameter write is performed from the communication option, write to RAM is enabled. Set when
frequent parameter changes are necessary.
Parameter
Number
Communication EEPROM write
342
⋅ When changing the parameter values frequently, set "1" in Pr. 342 to write them to the RAM.
Performing frequent parameter write with "0 (initial value)" (EEPROM write) set will shorten the life of the
EEPROM.
REMARKS
• 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 EEPROM
previously.
