REMARKS
• The above inverter reset using RY1A is available only when an inverter error occurs.
When Pr. 349 Communication reset selection = "0", inverter reset is available independently of the operation mode.
• Select Network operation mode to reset the inverter by setting data (H9696) in the instruction code (HFD) and then turn ON the
instruction code execution request (RYF). (Refer to page 69 for programming examples.)
• Refer to page 110 for operation conditions of inverter reset.
