Hello friends!
Continuing the series of articles on how to use Samkoon HMI to control different devices using the Modbus-RTU communication protocol, today plc247.com will guide you to control the LS iG5A inverter using this protocol.
Both the Samkoon HMI and the LS iG5A inverter have a built-in RS485 communication port for convenient Modbus-RTU connection.
Samkoon HMI & LS iG5A “Connection Diagram”
+ Below is the RS485 communication connection diagram between the Samkoon HMI and the LS iG5A Inverter
LS iG5A Modbus Parameters Setting
To be able to control the LS iG5A inverter using the Modbus-RTU protocol, we need to set the following communication parameters:
In this Project I install as follows:
+ Drv = 3
+ Frq = 7
+ I59 = 0 (Choose Modbus-RTU)
+ I60 = 1 (Slave No.1)
+ I61 = 3 (baudrate 9600bps)
+ I62 = 0
+ I65 = 2 (Even/1bit)
LS iG5A Modbus Registers Address
Note: LS iG5A Inverter Modbus RTU Address = “VFD Address – 1”
>>> Frequency Setting Address = 5 – 1 = 4 (dec)
>>> VFD Control Address = 6 – 1 = 5 (dec)
+ Set Word “5” = 2 >>> Run Forward
+ Set Word “5” = 4 >>> Run Reverse
+ Set Word “5” = 0 >>> Stop
>>> Current Output Address = 9 – 1 = 8 (dec)
>>> Frequency Output Address = A (hex) = 10 (dec) – 1 = 9 (dec)
>>> Voltage Output Address = B (hex) = 11 (dec) – 1 = 10 (dec)
HMI Samkoon “Modbus-RTU” Configuration
We need to set the communication parameters for the HMI exactly the same as the LS iG5A inverter
HMI Programming
+ Interface Panel
+ Set Frequency Command
+ “Forward Run” Command
+ “Reverse Run” Command
+ Stop Command
+ Read Output Frequency
+ Read Output Current
+ Read Output Voltage
