P15.00
Communication Protocol
Selection
0: Modbus
0
●
This parameter is used to select the inverter serial communication protocol type of communication.
P15.01
Local Address
0: Broadcast address
1~247: Slave address
1
○
When the host is writing data frame, the slave communication address set to 0, as the broadcast
address, all the salves from Modbus will accept the frame but slaves without response.
The machine address has uniqueness in the communication network, which is to achieve the basis of
point to point communication of HOST pc and inverter.
Note: when you need to read the inverter run data, the slave address cannot be set as 0.
P15.02
Baud Rate
0: 1200bps
1: 2400bps
2: 4800bps
3: 9600bps
4: 19200bps
5: 38400bps
6: 57600bps
7: 115200bps
3
○
This parameter is used to set data transfer rate between the HOST PC and inverter. Note: the HOST
pc and inverter set baud rate must be the same, otherwise, the communication can't be done. The
bigger the baud rate is, the faster the communication speed is. But it is easy to be interfered by
external environment, please choose according to peripheral environment.
P15.03
Data Format
0: No verify (N, 8, 1), for RTU
1: Even verify (E, 8, 1), for RTU
2: Odd verify (O, 8, 1), for RTU
3: No verify (N, 8, 2), for RTU
4: Even verify (E, 8, 2), for RTU
5: Odd verify (O, 8, 2), for RTU
0
○
This parameter is used to set the communication format between HOST PC and inverter. HOST PC
and inverter setting data format must be the same, otherwise, communication cannot be done.
P15.04
Response Delay
0ms~200ms
5ms
○
Response delay time: refers to the interval time from inverter data receipt ends to sending response
data to HOST PC. If response delay is less than system disposal time, then response delay take
system disposal time as reference, if response delay is longer than system disposal time, then after
system disposal of date, then waiting delay until response delay time arriving to send out data to
HOST PC.
P15.05
Communication Timeout
Detection Time
0.0s: No detection
0.1s~100.0s
0.0s
○
When the function code is set to 0.0 s, communication timeout parameter is Disabled. When the
function code set to enabled values, if the interval time between a communication and the next
communication beyond the communication timeout, system will be submitted to the communication
failures Er018. Usually, it is set into is disabled. If in the continuous communication system, set this
