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 page 7-2.
The reply code at the time of instruction code execution is set to D2.
(For information about the reply code (RWr2) refer to page 6-360.)
Resetting the inverter at inverter error
The following is a program example for resetting station 1 inverter.
I003137E
Fig. 6-184: Program example 8
I003138E
Fig. 6-185: Program example 9
NOTES 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 exam-
ple, refer to page 6-367.)
Refer to page 6-243 for operation conditions of inverter reset.
