NOTE
• The inverter reset with the flag RY3A 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 (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

5.21.6 Instructions

 Programming instructions
• Since the buffer memory data of the master station is kept transferred (refreshed) to/from the inverters, the TO instruction
need not be executed every scan in response to data write or read requests. (The execution of the TO instruction every
scan does not pose any problem.)
• If the FROM/TO instruction is executed frequently, data may not be written reliably. When transferring data between the
inverter and sequence program via the buffer memory, perform the handshake to confirm that data has been written
without error.
