8001
0000: no fault
0001: password erro
0002: command code erro
0003: CRC check erro
0004: invalid address
0005: invalid parameter
0006: parameter change is invalid
0007: system is lock
0008: in EEPROM operation
Fd MODBUS Communication
Fd-00
Baud Rate
0: 300BPS
1: 600BPS
2: 1200BPS
3: 2400BPS
4: 4800BPS
5: 9600BPS
6: 19200BPS
7: 38400BPS
8: 57600BPS
9: 115200BPS
5
○
This parameter is used to set data transfer rate between the PC and inverter.
Note that the host
computer and the baud rate set by the inverter must be the same, otherwise, communication can not
be carried out.The higher the baud rate, the faster the communication speed.
Fd-01
Data Format
0: No verify (8-N-2)
1: Even verify (8-E-1)
2: Odd verify (8-O-1)
3: 8-N-1
0
○
The host computer and the data format set by the inverter must be the same, otherwise,
communication can not be carried out.
Fd-02
Local Address
0: is broadcast address
1~247: slave address
1
○
When the machine address is set to 0, namely for the broadcast address, to achieve PC broadcast
function.
The machine address is unique (except broadcast address), which is to achieve the basis of the PC
and inverter point-to-point communications.
Fd-03
Response Delay
0ms~20ms
2ms
○
Response delay: refers to the middle interval time of the inverter data reception ends to the host to
send data. If the response delay is less than the system processing time, the response delay is based
on the system processing time,
if the response delay is longer than the system processing time, after
the system processing the data, to delay the wait until the response delay time to send data to the
host computer.
Fd-04
Communication
Timeout Time
0.0 (disabled)
0.1s~60.0s
0.0s
○
When the function code is set to 0.0 s, communication timeout time parameter is invalid.
