This parameter is used to set the data transfer rate from host computer and the frequency
inverter. Please note that baud ratio of the host computer and the inverter should be consistent.
Otherwise, the communication is impossible. The higher the baud ratio is, the faster the
communication is.
Pd-01
Modbus data
format
Default
0
Setting Range
0: No check, data format <8,N,2>
1: Even parity check, ataformat<8,E,1>
2: Odd Parity check, ataformat<8,O,1>
3: No check, data format <8,N,1>
Valid for Modbus
The host computer and frequency inverter setup data format must be consistent, otherwise,
communication is impossible.
Pd-02
Broadcast address
Default
1
Setting Range
1~247
，
0 is broadcast address
When the local address is set to 0, that is, broadcast address, it can realize the broadcast
function of host computer.
Pd-03
Modbus response delaytime Default
2ms
Setting Range
0~20ms
After the data is finished, wait until the response delay time expires before sending data
to the host computer.
。
Pd-04
Communication timeout
Default
0.0 s
Setting Range
0.0 s
（
Invalid
）
0.1~60.0s
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
