5: 38400BPS
6: 57600BPS
7: 115200BPS
Note:
The baud rate set on the VFD must be
consistent with that on the upper computer.
Otherwise, the communication fails. A greater
baud rate indicates faster communication.
P14.02
Data bit check
The data format set on the VFD must be
consistent with that on the upper computer.
Otherwise, the communication fails.
0: No check (N, 8, 1) for RTU
1: Even check (E, 8, 1) for RTU
2: Odd check (O, 8, 1) for RTU
3: No check (N, 8, 2) for RTU
4: Even check (E, 8, 2) for RTU
5: Odd check (O, 8, 2) for RTU

P14.03
Communication
response delay
0–200ms
The function code indicates the
communication response delay, that is, the
interval from when the VFD completes
receiving data to when it sends response data
to the upper computer. If the response delay is
shorter than the VFD processing time, the
VFD sends response data to the upper
computer after processing data. If the delay is
longer than the VFD processing time, the VFD
does not send response data to the upper
computer until the delay is reached although
data has been processed.

P14.04
Communication
timeout time
0.0 (invalid)–60.0s
When the function code is set to 0.0, the
communication timeout time is invalid.
When the function code is set a non-zero
value, the rectifier reports the "
Modbus/Modbus TCP communication fault"
(CE) if the communication interval exceeds
the value.
In general, the function code is set to 0.0.
