F9Group - Communication parameter description
F9.00
Baud rate
Default
6005
Setting range
Units digit: MODUBUS baud rate
0: 300BPS
1: 600BPS
2: 1200BPS
3: 2400BPS
4: 4800BPS
5: 9600BPS
6: 19200BPS
7: 38400BPS
8: 57600BPS
9: 115200BPS
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, 0for 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.
