I
This parameter is used to set the data transfer rate between the host computer and the inverter.
Note: the baud rate must be set to the same for the host computer and the inverter, otherwise
communication can not be achieved. The larger baud rate, the faster communication speed.
F9.01
Data format
Default
0
Setting range
0: no parity: data format <8, N, 2>
1: even parity: data format <8, E, 1>
2: odd parity: data format <8, O, 1>
3: no parity: data format <8-N-1>
Note: the set data for the host computer and the inverter must be the same.
F9.02
This unit address
Default
1
Setting range
1 to 247, 0 for broadcast address
When the address of this unit is set 0, that is broadcast address, the broadcasting function for the
host computer can be achieved.
The address of this unit has uniqueness (in addition to the broadcast address), which is the basis
of peer-to-peer communication for the host computer and the inverter.
F9.03
Response delay
Default
2ms
Response delay
0~20ms
Response delay: refers to the end of the frequency converter data to the host computer to send
data in the middle of the interval. If the response delay is less than the system processing time,
delayed response to system processing time shall prevail, such as response delay is longer than the
system processing time, system processed data, to the delay of waiting, until the response delay time
to, to send data to the host computer.
F9.04
Communication
timeout
Factory value
0.0 s
Response delay
0.0s (invalid); 0.1~60.0s
When the function code is set to 0.0s, the communication timeout time parameter is invalid.
When the function code is set to a valid value, the system will report the fault fault (fault
sequence number Err.16) if the communication time between the next communication and the next
communication time exceeds the communication time. Usually, they are set to invalid. If you are in a
continuous communication system, set the secondary parameters, you can monitor the status of the
communication.
F9.05
Communication protocol
selection
Factory value
1
Response delay
0: non standard Modbus protocol;
1: Standard Modbus protocol
F9.05=1: Select standard Modbus protocol.
F9.05=0: Read command, the return of the number of bytes from the machine is more than one
byte of the standard Modbus protocol.
F9.06
Communication read
current resolution
Factory
value
0
Response delay
0: 0.01A; 1: 0.1A
The output unit of the current value is used to determine the output current of the communication
read output.
