Ethernet communication (FR-A800-E)
Programming example for fault record reading
The following program reads the fault records of the station 1 inverter to output to D1.
● Faults history No. 1 and 2 reading instruction code: H74 (hexadecimal)
For the error code, refer to page 6-5.
The reply code at the time of instruction code execution is set to D2. (Refer to page 5-821.)

NOTES The inverter reset with the flag RY1A shown above is enabled at an inverter fault only.
When Pr. 349 "Communication reset selection" = "0", an inverter reset can be made in any opera-
tion 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. (Refer to program
example 2 on page 5-825).
Refer to page 5-633 for operation conditions of inverter reset.
