HMI Proface “Modbus RTU” Fuji Frenic Tutorial

Hello friends! Fuji Frenic Series is one of the most popular inverters in Japanese machines. With many outstanding advantages and diverse applications, this is a suitable choice for any machine.

Today plc247.com will guide you to implement a project using HMI Proface GP4402WW to connect and control Fuji Frenic VFD through Modbus RTU (RS485) Communication.

FUJI Frenic Modbus RTU Parameters Setting

In addition to the basic parameters of the inverter (Frequency, voltage, current…) to be able to control the inverter with Modbus RTU we need to install the following parameters:

• 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

Registers Address Table

Note: GP4402WW HMI Address = “400001 (dec) + Device Address”

• Frequency Setting Address = S(07H) + 05 = 705 (hex)
  >>> HMI Address = 400001(dec) + 705(hex) = 400001(dec) + 1797(dec) = 401798

• Motor Control Address = S(07H) + 06 = 706 (hex)
  >>> HMI Address = 400001(dec) + 706(hex) = 400001(dec) + 1798(dec) = 401799

+ Set Word 401799 = 1 >>> Forward Run
= 2 >>> Reverse Run
= 0 >>> Stop

Monitoring

• Output Frequency Address = M(08H) + 09 = 809(hex)
  >>> HMI Address = 400001(dec) + 809(hex) = 400001(dec) + 2057(dec) = 402058
• Output Voltage Address = M(08H) + 12 = 80C(hex)
  >>> HMI Address = 400001(dec) + 80C(hex) = 400001(dec) + 2060(dec) = 402061
