Whether the function code written by the communication method is saved to EEPRO
Set value
Whether the function code written by the communication method is saved to EEPROM
0
Do not write to EEPROM, and do not save data after power failure;
1
Write to EEPROM, and save data after power failure;
✎Note: If you need to change the function code value frequently, it is recommended to set the function code to
0, otherwise the EEPROM would be damaged due to frequent erase of EEPROM. “Er.02” (Parameter Storage
Error) will occur on the servo drive.
