Hello friends!
Fuji Frenic inverter is a commonly used inverter on the market and it originated in Japan, today plc247.com will guide you to use Samkoon HMI to control it through Modbus-RTU protocol.
In this project I use Fuji Frenic Mini (Similar Multi, Mega, Eco models) and HMI Samkoon SK-070HS.

Fuji Frenic “Modbus RTU” Parameters Setting
We need to set the following communication parameters so that the Fuji Frenic inverter can be controlled via Modbus-RTU protocol:
- H30 = 3 (VFD Control via RS485 Port)
- Y01 = 1 (Slave Address)
- Y02 = 0
- Y03 = 2
- Y04 = 2 (9600bps)
- Y05 = 0 (Data: 8bit)
- Y06 = 1 (Parity Check: Even)
- Y07 = 1 (Stop Bit: 1)
- Y10 = 0 (Modbus-RTU Selection)
- Y99 = 0

Fuji Frenic Modbus Registers Address
+ Frequency Reference Address = S(07H) + 05 = 705 (hexa) = 1797 (dec)
+ Operation Command Address = S(07H) + 06 = 706 (hexa) = 1798 (dec)
- Set Word “1798” = 1 >>> Forward Run
= 2 >>> Reverse Run
= 0 >>> Stop Run
+ Output Frequency Address = M(08H) + 09 = 809 (hexa) = 2057 (dec)
+ Output Current Address = M(08H) + 11 = 80B (hexa) = 2059 (dec)
+ Output Voltage Address = M(08H) + 12 = 80C (hexa) = 2060 (dec)
Samkoon HMI Modbus Configuration
In order for the Samkoon HMI to control the Fuji Frenic inverter, we need to set the Modbus communication parameters same between the two devices
