Notes

As for the EEPROM parameter, first the data is written to RAM, after that the data is written to EEPROM. Some EEPROM parameters cannot be changed during the inverter is running.

When write to EEPROM parameter that will change inverter status from stop to run, the inverter must be in the state that it cannot run.

For example: To write to EEPROM, the inverter must open ST-CC. (display shows "OFF") If not, the data is only written to RAM.

The Life of EEPROM is approximately 100,000 times. Avoid writing a command more than 100,000 times to the same parameter of the Inverter.

Please access only parameters in document.
