Pd group communication parameters description
Pd-00
Baud rate
Default
6005
Setting range
Digital’s bit: MODBUS Baud rate
0
：
300BPS
1
：
600BPS
2
：
1200BPS
3
：
2400BPS
4

4800BPS
5

19200BPS
7

38400BPS
8
：
57600BPS
9
：
115200BPS
This parameter is used to set the data transfer rate between the host computer and the inverter.
Caution: The baud rate of the position machine and the inverter must be consistent.
Or, communication is impossible. The higher the baud rate is, the faster the communication is.
Pd-01
Data format
Default
0
Setting range
0
：
No check: data format <8,N,2>
1
：
Even parity check: data format <8,E,1>
2
：
Odd parity check: data format <8,O,1>
3
：
No check: data format <8-N-1>
The data format of the position machine and the inverter setup must be consistent, otherwise communication
is impossible.
Pd-02
Local address
Default
1
Setting range
1~247
，
0 is broadcast address.
When the local address is set to 0, that is the broadcast address, achieve position machine’s broadcast
function. The local address is unique (except for the broadcast address), which is the basis for the position
machine and the inverter point to point communication.
Pd-03
Response delay
Default
2ms
Setting range
0~20ms
Response delay: It refers to the interval time from the inverter finishes receiving data to sending data to the
position machine. If the responses delay is less than the system processing time, the response based on the
time delay of the system processing time. If the response delay is more than the system processing time, after
the system process the data, it should be delayed to wait until the response delay time is up, then sending
data to host machine.
