JT550 Series Inverter Manual
Fd.01
The data format of host has to match that of inverter. Otherwise, the communication will fail.
Fd.02
When the address of this inverter is set to 0, it is the broadcasting address and able to broadcast by
the host.
The address of this inverter is unique (except the broadcasting address), which is the foundation of
point-to-point communication between the host and inverter.
Fd.03
Response Delay: It indicates the time interval between the end of inverter receiving data and sending
it to the host. If the response delay is less than the time of system processing, then the delay is consistent
with the time of system processing; if the response delay is larger than the time of system processing, then
it will have to wait until the response time is reached and sends data to the host.
Fd.04
When the function code is set to 0.0s, the parameter becomes invalid.
When this function code is set as valid, if the time interval between this communication and next
communication is larger than the communication over-time, it will report communication error (Err16).
Usually it is set as invalid. This parameter can also be set to monitoring the status of communication in a
system of continuous communication
Fd.05
Fd.05=1: Select standard Modbus protocol.
Fd.05=0: Select non-standard Modbus protocol. When reading commands, the number of the bytes
received from the slave is one byte longer than the standard Modbus protocol
Fd.06
It determines the output unit of current value when communication reading the current.
