When the communication signal is lost for a period longer than the
setting of this parameter, the inverter deems that communication fault
occurs.
When it is set at 0, the inverter will not detect the signals at the serial
port, i.e., this function is invalid.
Response delay refers to the time from the inverter receiving and
executing the command of the host to returning reply frame to the host.
For RTU mode, the actual response delay should be no less than 3.5
bytes’ transmitting time.

Note: If master, usually used in multi-inverter interaction applications.
This parameter applies only to the slave, used for setting from the
receiving master given correction coefficient.

Simple PLC is a multi-speed generator, through which, the inverter can
change frequency and direction according to the running time. This
function is realized through PLC (programmable logic controller) before,
now the inverter can do it by itself. See Figure 6-67.
