Mitsubishi Electric FR-A800 Series Instruction Manual page 770

*1 To the EEPROM, a writing is performed only once after the command Y1022 turns ON.
*2 If the set data is changed at the command Y1022 ON, the change is not applied to the inverter.
 Programming example for the fault record reading
The following program reads the fault records of the station 1 inverter to output to D1.
• Fault history No. 1 and 2 reading instruction code: H74 (hexadecimal)
For the error code, refer to
The reply code (RWr10) to the instruction code execution is set in D2. (Refer to

NOTE
• The inverter reset with the flag RY3A shown above is enabled at an inverter fault only.
• When Pr.349 Communication reset selection/Ready bit status selection = "0 or 100", inverter reset is available
independently of the operation mode.
• When using the instruction code execution request (RY25) with the instruction code (HFD) and data (H9696) to reset the
inverter, set a value other than "0" in Pr.340 Communication startup mode selection or change the operation mode to the
Network operation mode. (For the program example, refer to
