Goodrive270 series VFD for fan and pump Function parameter list
-230-
P14 group––Serial communication
Local
communication
address
Setting range: 1–247
When the master writes the slave
communication address to 0 indicating a
broadcast address in a frame, all the salves on
the Modbus bus receive the frame but do not
respond to it.
The communication addresses on the
communication network are unique, which is the
basis of the point-to-point communication.
Note: The communication address of a slave
cannot be set to 0.
The function code is used to set the rate of data
transmission between the upper computer and
the VFD.
0: 1200BPS
1: 2400BPS
2: 4800BPS
3: 9600BPS
4: 19200BPS
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.
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
