Local communication
P14.00
address
When the master is at write frame and the communication address of the slave is set to 0 (broadcast
communication address), all the slaves of the MODBUS will accept the frame without response.
Local communication address is unique in communication network and it is the foundation to achieve
point-to-point communication between the upper computer and inverter.
Note: The address of the slave cannot be set to 0.

Communication
P14.01
baud rate
Set the data baud rate between the upper computer and inverter.
Note: The baud rates set by the upper computer and inverter should agree with each other;
otherwise, the communication is disabled. The larger the baud rate is, the faster the
communication is.

response delay
The function code refers to the interval when the inverter receives data and sends response to the upper
computer. If the response delay is shorter than the processing time, take the processing time as the
standard. If the response delay is longer than the processing time, delay and wait to send data to the
upper computer until the response delay arrival after the system finishes processing data.
