Simple instruction for using Modbus communication
Only in remote mode, the frequency converter can be controlled through Modbus communication.
Below are the key points to use the Modbus communication control.
1)
First, please check the parameters P0-80~P 0-82 to be consistent with the communication
settings of host computer. P0-80 is the slave address of the frequency converter (default value is
1). Parameter P0-81 is the communication baud rate (default value is 9600). P0-82 is the
communication data format, which defaults to even-check bits and one stop bit. These three
parameters can also be changed according to the communication parameters of the host
computer. The communication parameters of the host computer and the frequency converter
must be set to the same.
2)
Writing command in register address 9999 to start/stop the frequency converter, and writing
value in register address 10000 to control the output frequency of the converter. Please refer to
Appendix A for the detailed instructions.
A typical wiring set up is shown as below:
5.6. Reset the parameters to Factory Defaults
Set parameter P7-00 = 9;
Power down the product fully and power on again, the keypad shows A.01
Press the “STOP” key to clear the A.01, then the parameters are reset to factory defaults except
for the parameter group 8 and group 9.
