7.4 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 converter uses the serial port COM1,
but COM2 is selected for the communication.

The settings of the baud rates, data bits, stop 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 RS485 wire cap on the terminal board of the VFD is not connected. This wire cap is
at the back of the terminal block.
