
For EEPROM, write is made only once when Y100E is switched on.

If the set data is changed with Y100E on, it is not reflected on the inverter.
 Program example for fault record reading
The following program reads fault records of station 1 inverter to D1.
• Faults history No. 1, No. 2 reading instruction code: H74 (hexadecimal)
For the error codes, refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.
The reply code at the time of instruction code execution is set to D2. (Refer to

NOTE
• The above inverter reset using RY1A may be made only when an inverter error occurs. When Pr.349 Communication reset
selection = "0", inverter reset is available independently of the operation mode.
• When using the instruction code execution request (RYF) 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
• Refer to page 18
