call up "Properties - PC COM-Port (USS)".
Figure 4-8 PC COM properties
● In this dialog box, you can set the COM interface (COM1, COM2, COM3) and baud rate
(default: 38400).
● To determine the correct values of your interface, choose e.g. COM1, and then click on
"Read".
● Under the "RS 485" tab, in addition, select the "Automatic mode". Using various baud
rates in succession, the PC checks whether communications have been established to
the inverter. This can take several minutes.
● If "???" is displayed in the Baud rate test field then the baud rate test was unsuccessful.
and you should choose a different COM interface. In the case of the correct COM
interface, a value is displayed. Enter this value into the "baud rate" selection field.
