User Parameter Eeprom Read/Write Method - Mitsubishi Electric FR - F700 Programming Manual

1.12.2 User parameter EEPROM read/write method

Parameter
Device No.
No.
D110 to 506 to 515,
D159 826 to 865
After turning off the read/write command and on again, turning on the read/write
completion enables read/write of user parameter from RAM and EEPROM.

REMARKS
•Even if a user parameter is changed by direct write (RAM value write), executing data read
from EEPROM changes a RAM value to the value stored in EEPROM.
•When Pr.342 Communication EEPROM write selection = "1", a RAM value is written/read.
