Parameter Name 

Setting Range 

Default 

2: Odd Parity check, data format<8,O,1> 

3: No check, data format <8,N,1> 

The host  computer  and 

variable frequency drive

 setup  data  format  must  be consistent,  otherwise,

communication  is impossible.

Parameter Name 

Setting Range 

Default 

Fd-02 

Broadcast address 

0~247    (0: Broadcast address) 

When the local address is set to 0, that is, broadcast address, it can realize the broadcast function of host computer.

Setting Range 

Default 

Fd-03 

Modbus response time  0~20 ms 

2 ms 

Response delay time: it refers to  the interval time from the inverter finishes receiving data to sending data to the 

host machine. If the response time is less than the system processing time, then the response delay time is based on 

the time delay of the system processing time. If the response delay time is more than the system processing time, 

after  the  system  processes  the  data,  it  should  be  delayed  to  wait  until  the  response  delay  time  is  reached,  then 

sending data back to host machine.

Parameter Name 

Setting Range 

Default 

Fd-04 

Communication 

timeout 

0.0s:invalid 

0.1s~60.0s 

0.0s 

When the function is set to 0.0s, the communication interface timeout parameter is invalid. 

When  the  function  code  is  set  to  time  value,  if  the  interval  time  between  the  communication  and  the  next 

communication is beyond the communication timeout, the system will report communication failure error (Err16). 

At normal circumstances, it will be set as invalid. If in the continuous communication system, set this parameter, 

you can monitor the communication status.

transmission format 

selection 

Unit's digit: Modbus protocol. 

0: Non-standard Modbus protocol 

1: Standard Modbus protocol 

Fd-05=1: Select standard Modbus protocol. 

Fd-05=0:  When  reading  the  command,  the  slave  machine  return  is  one  byte  more  than  the  standard  Modbus 
protocol’s, for details, refer to communication data structure of this protocol.
