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).)
Programming example for resetting the inverter at an inverter fault
The following program resets the station 1 inverter at an inverter fault.

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).
