Click Send. If the line configuration and settings are correct, a response transmitted by the VFD is received

as follows.

8.5 Common communication faults

Common communication faults include the following:
No response is returned.

The VFD returns an exception response.

Possible causes of no response include the following:
The serial port is set incorrectly. For example, the adapter uses the serial port COM1, but COM2 is selected for the

communication.
The settings of the baud rates, data bits, end bits, and check bits are inconsistent with those set on the VFD.

The positive pole (+) and negative pole (-) of the RS485 bus are connected reversely.

The resistor connected to 485 terminals on the terminal block of the VFD is set incorrectly.
