Appendix II
F9 Group - Communication parameter description
F9.00
This parameter is used to set the data transfer rate between the host computer and the inverter. Note:
the baud rate must be set to the same for the host computer and the inverter, otherwise
communication can not be achieved. The larger baud rate, the faster communication speed.
F9.01
Note: the set data for the host computer and the inverter must be the same.
This unit address
F9.02
When the address of this unit is set 0, that is broadcast address, the broadcasting function for the
host computer can be achieved.
The address of this unit has uniqueness (in addition to the broadcast address), which is the basis of
peer-to-peer communication for the host computer and the inverter.
Response delay
F9.03
Response delay: it refers to the interval time from the end of the inverter receiving data to the start
of it sending data to the host machine. If the response delay is less than the system processing time,
then the response delay time is subject to the system processing time; If the response delay is
longer than the system processing time, after the system finises the data processing, and continues
to wait until the response delay time, and then sends data to the host computer.
