5: Odd parity (O, 8, 2) for RTU
Communication
response delay
0–200ms
It refers to the time interval from when the data is
received by the VFD to the moment when the data is sent
to the controlling computer. If the response delay is less
than the system processing time, the response delay will
be subject to system processing time; if the response
delay is longer than the system processing time, data will
be sent to the controlling computer at a delay after data
process is done by system.
RS485
Communication
timeout period
0.0 (invalid) –60.0s
This parameter will be invalid if it is set to 0.0;
When it is set to a non-zero value, if the time interval
between current communication and the next
communication exceeds the communication timeout
period, the system will report "Modbus/Modbus TCP
communication fault" (CE).
Under common situations, it is set to 0.0. In systems
which have continuous communication, users can
monitor the communication condition by setting this
parameter.
