<Timing chart when writing to RAM>
*1 To the EEPROM, a writing is performed only once after the command Y100E turns ON.
*2 If the set data is changed at the command Y100E ON, the change is not applied to the inverter.
 Programming example for the fault record reading
The following program reads the fault records of the station 1 inverter to output to D1.
• Fault history No. 1 and 2 reading instruction code: H74 (hexadecimal)
For the error codes, refer to the Instruction Manual (Maintenance).
The reply code to the instruction code execution is set in D2. (Refer to

NOTE
• The inverter reset with the flag RY1A shown above is enabled at an inverter fault only.
• When Pr.349 Communication reset selection = "0", inverter reset is available independently of the operation mode.
• When using the instruction code execution request (RY0F) 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

Check the data link status of the station 1
Write error history No.1 and No.2 read
code (H74) to RWw2.
Turn on the instruction code execution request
(RY0F)
Read alarm data (RWr3) and reply code
(RWr2) to D1 and D2 when the instruction
code execution completion (RX0F) turns on.
Turn off the instruction code execution request
(RY0F)
Check the data link status of the station 1
Turn on the error reset request flag (RY1A)
Turn off the error reset request flag (RY1A)
when the error status flag (RX1A) is off.
