 Selecting the operation mode for power-ON (Pr.340)
• Depending on the Pr.79 and Pr.340 settings, the operation mode at power-ON (reset) changes as described below.

*1 Use Pr.340 = "2 or 12" setting to perform communication with the RS-485 terminals. Even if an instantaneous power failure occurs while Pr.57
Restart coasting time ≠ "9999", the inverter continues running at the condition before the instantaneous failure. When Pr.340 = "1 or 10", if a
power failure occurs while the start signal is being input through communication, the start signal is OFF at power restoration.
*2 The operation mode cannot be directly changed between the PU operation mode and Network operation mode.
*3 Switching between the PU and NET operation modes is available with the
