* The parameters can be set when Pr. 160 User group read selection = "0". However, the parameters can be set whenever the communication option
is connected. (Refer to page 146.).

*1 The Pr. 340 setting "2" or "12" is mainly used for communication operation using the inverter RS-485 terminals. 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.
*2 The operation mode cannot be switched directly between the PU operation mode and network operation mode.
*3 Operation mode can be changed between the PU operation mode and network operation mode with
X65 signal.
