Programming example for the 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 (RWr10) to the instruction code execution is set in D2.
(Refer to page 5-756 for the reply code (RWr10).)

NOTES The inverter reset with the flag RY3A 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 (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. (Refer to pro-
gram example 2 on page 5-763).

Programming example 8
Check the data link status of the station 1.
M0
Write the faults history No.1 and No.2 read code (H74) to
W110
RWw10.
Turn ON the instruction code execution request (RY25).
Read the fault record (RWr11) and the reply code (RWr10)
to output to D1 and D2 when the instruction code
execution completion (RX25) turns ON.
Turn OFF the instruction code execution request (RY25).
END
Check the data link status of the station 1.
M0
Turn ON the error reset request flag (RY3A).
Y103A Turn OFF the error reset request flag (RY3A) when the error
status flag (RX3A) is OFF.
