Hello friends, today thelivingchristmascompany.com will guide you to use Weintek MT8071iE HMI to control FUJI Frenic inverter via Modbus-RTU communication standard.

• HMI MT8071iE Weintek “Modbus-RTU” LS iG5A VFD
• Mitsubishi FX3U & Fuji Frenic “Modbus” Tutorial

I use HMI’s COM3 port to connect directly to the inverter via RJ-45 port (Depending on the built-in Frenic inverter model or RS-485 card must be used)

Fuji Frenic Inverter Configuration

You need to configure the following communication parameters (I use 9600/8/1/E)

• H30: 3 ( Use RS485 Port)
• Y01: 1 (Station No.1)
• Y02: 0
• Y03: 2
• Y04: 2 (9600bps)
• Y05: 0 (Use 8bit)
• Y06: 1 (Even)
• Y07: 1 (Stop bit =1)
• Y10: 0 (Modbus-RTU)
• Y99: 0

Register Address Table Layout

Each group of Modbus addresses will correspond to a different Hex address

Register for Control VFD

With HMI MT8071 Address Use = “Register Address + 1“

+ Frequency Set Address (S05) = 07 + 05 = 705 (Hex) = 1797 (Dec)
>>> Address Use = 1797 + 1 = 1798 (Dec)

+ VFD Control Address (S06) = 07 + 06 = 706 (Hex) = 1798 (Dec)
>>> Address Use = 1798 + 1 = 1799 (Dec)

• Set 1799 (Dec) = 1 >>> Motor Run Forward
• Set 1799 (Dec) = 2 >>> Motor Run Revese
• Set 1799 (Dec) = 0 >>> Motor Stop

Register for Data Response

+ Output Frequency Address (M08) = 08 + 09 = 809 (Hex) = 2057 (Dec)
>>> Address Use = 2057 + 1 = 2058 (Dec)

+ Output Voltage Address (M12) = 08 + 0C = 80C (Hex) = 2060 (Dec)
>>> Address Use = 2060 + 1 = 2061 (Dec)
