Message transmission and receive timings on the RS485 communication interface
When the RS485 communication interface is connected by 2-wire method, it will be half-duplex
communication line. Therefore, when transmitting and receiving a message, the computer should use the
timing described below when sending a collision between computer-sent and inverter-sent messages.

Specified command inverter‘s response selection
In order to improve communication speed, the response sent by inverter can be selected.
The communication formats of ASCII and BINARY will not return a response from an inverter to the
following commands. The error response can also be selected.
F4011=0: Sent
=1: Not sent (error response sent)
=2: Not sent (error response not sent)
