7. Communications parameters
The settings of communication-related parameters can be changed from the operation panel and the
external controller (computer). Note that there are two types of parameters: parameters whose set-
tings take effect immediately after the setting and parameters whose settings do not take effect until
the inverter is turned back on or reset.
