*1 Operation mode can not be directly changed between the PU operation mode and network operation mode.
*2 The Pr. 340 settings "2, 12" are mainly used for communication operation using the inverter RS-485 terminal.
When a value other than "9999" (selection of automatic restart after instantaneous power failure) is set in Pr. 57 Restart coasting time, the
inverter will resume the same operation state which was in before after power has been restored from an instantaneous power failure. When
Pr.340 = "1, 10", run command from communication turns off after instantaneous power failure.
*3 Operation mode can be changed between the PU operation mode and network operation mode with
DU07) and X65 signal.
*4 Pr. 79 = "6" and Pr. 128 to Pr. 134 (PID control) are not activated simultaneously. Switchover mode and PID control are made invalid, and
the inverter performs the same operation as when "0" is set in Pr. 79.
