 Programming example for fault record reading
The following program reads fault records of station 1 inverter to D1.
• Fault history No. 1, No. 2 reading instruction code: H74 (hexadecimal)
For the error code, refer to the Instruction Manual (Detailed) of the inverter.
The reply code at the time of instruction code execution is set to D2. (RWr10: Refer to

NOTE
• The above inverter reset using RY3A may be made only when an inverter error occurs.
When Pr.349 Communication reset selection/Ready bit status selection/Reset selection when inverter errors cleared
is set to "0, 100, 1000, or 1100", inverter reset is available in any operation 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. (For the program example, refer to
(N) Operation via communication and its settings
