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 in will shorten the life of
the EEPROM.
REMARKS
When "1" is set in Pr. 342 (write to RAM only), 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.
