PARAMETERS
4.18.2 Operation mode at power-on (Pr. 79, Pr. 340)
(1) Specify operation mode at power-on (Pr. 340)
Depending on the Pr. 79 and Pr. 340 settings, the operation mode at power-on (reset) changes as described below.
When power is switched on or when power comes back on after instantaneous power failure, the inverter can be
started up in the network operation mode.
After the inverter has started up in the network operation mode, parameter write and operation can be performed from
a program.
Set this mode for communication operation using PU connector.
