FB Communication Parameter
FB.00
Communication protocol
0 ~ 1
0
Communication protocol selection
0: MODBUS
1: user-defined
FB.02
Baud rate setting
0 ~ 5
3
0: 2400BPS
1: 4800BPS
2: 9600BPS
3: 19200BPS
4: 38400BPS
5: 115200BPS
This function code is used to define the data
transmission rate between host and VFD. The
baud rate setting of host should be in accord
with that of VFD, or the communication will go
wrong. The larger of the baud rate, the quicker
of the response, but too larger of the setting
value may affect the communication stability.
FB.01
Local address
0 ~ 247
1
0: broadcasting address
1 ~ 247: slave station
During 485 communication, the parameter
can identify local driver's address.
Notice
"0" is the broadcasting address. When it
is set so, the slave can receive and execute
the command by host, but will not answer
back.
4.2 Detailed Function Description
0: no parity(N, 8, 1) for RTU
1: even parity(E, 8, 1) for RTU
2: odd parity(0, 8, 1) for RTU
3: no parity (N, 8, 2) for RTU
4: even parity(E, 8, 2) for RTU
5: odd parity(0, 8, 2) for RTU
Notice: ASCII mode is reserved at present
The host should keep the same data format
with the driver, or there will be fault for
communication.
FB.03
Data format
0 ~ 5
0
Response delay refers to the time from
the driver receiving the command of the
host to returning reply frame to the host.
If the response time is shorter than system
processing time, go with the system
processing time. Otherwise, the system will
send data to host after delay waiting time.
FB.04
Response delay
0 ~ 200ms
5
0: response to write operation
The driver will response to all read-write
commands of host.
1: not response to write operation
The driver will response to all read
command of the host, but not to the write
command, so as to improve communication
efficiency.
FB.05
Transmission response
0 ~ 1
