System Requirements
Simultaneously control three EDS1000 series inverters through a Kunlun open-state touch screen. It is required to control the forward/reverse/jog/stop of each inverter on the touch screen screen, change the frequency, display the running frequency, and output voltage. ,Motor speed;
The COM2 of the MCGS TPC7062KD touch screen supports the standard MODBUS RTU protocol. The port pins are defined as follows:
Touch screen and inverter wiring
Touch screen settings, select the universal serial port, and establish three MDBUS RTU sub-stations;
parameter settings
Set the universal serial port, baud rate 9600, 1-8-1, no calibration, this parameter should be consistent with the communication parameters of the inverter;
In the device editing window, "Device Address" = Inverter Communication Address, add variables to be controlled and monitored to "Connection Variable";
Touch screen monitoring screen;
Inverter parameter settings:
Set the following parameters of the inverter in advance:
F0.00=3 // serial port given
F0.02=3 // serial port running command control
F2.14=03 //Baud rate 9600, 1-8-1, no parity
F2.15=01 //Inverter address 1/2/3
The control commands and status communication addresses of the inverter are as follows:
