10.4.8.4 MODBUS communication commissioning example
Assume that the master is a PC which uses RS232-RS485 converter to convert signals. The
converter uses the PC serial port COM1 (RS232 port). The upper monitor commissioning software is
the serial port commissioning assistant Commix 1.4, which is available in the Internet. It is
recommended to use the software with the CRC function. The figure below shows an interface
example of the software.
Set "Port" to "COM2". Set "BaudRate" to the value the same as that of P14.01. Keep "DataBits",
"Parity", and "StopBits" consistent with the setting of P14.02. In RTU mode, select "HEX". If CRC
must be enabled, select "ModbusRTU" and "CRC16(MODBUSRTU)", and set the starting byte to "1".
Once after CRC is automatically enabled, you must not enter CRC in commands. Otherwise,
repeated setting will cause command errors.
The commissioning command below enables the inverter with the address set to 03H to rotate
