Appendix I H5RS485 Card & RS485Communication Protocol
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 Factory default value
0
Setup 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 Factory default value
1
Setup 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 Factory default value
2ms
Setup 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 response delay is less than the system processing
time, then 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.
Pd.04
Communication
Overtime
Factory default value
0.0 s
Setup range
0.0 s (Invalid)
0.1~60.0s
When the function set to 0.0s, the communication overtime parameter is invalid.
When the function code is set to valid value, if the interval time between one
communication with the next communication exceeded the communications overtime, the
system will report communication fault error (fault serial 16= E.CoF1) . Under normal
circumstances, it will be set to invalid value. If the system of continuous communication, setting
parameters, you can monitor the communication status.
