DELTA DVP 14SS2 “Modbus RTU” Fuji Frenic Tutorial

Written by

In the previous post, showed you how to use the Delta DVP-Series PLC to control the Mitsubishi FR-E700 Seires inverter via Modbus-RTU RS485 communication.

Today I would like to continue to guide you to use Delta PLC to control Fuji Frenic inverters (Mini, Eco, Mega, Multi… Series).

Note: If the communication distance is long (>50m), then a 120-Ohm . terminal resistor should be used

Fuji Frenic VFD Modbus Configuration

In addition to the basic parameters of the inverter, we need to set the communication parameters as follows:

+ H30 = 3 (Control via RS485 Port)

+ Y01 = 1 ( Slave No.1)

+ Y02 = 0

+ Y03 = 2

+ Y04 = 2 (9600bps)

+ Y05 = 0 (bit)

+ Y06 = 1 (Even)

+ Y07 = 1 ( Stopbit-1)

+ Y10 = 0 (Choose Modbus-RTU)

+ Y99 = 0

Register Address for Control

Looking at the table above we can see:

+ Frequency Reference = S(07Hex) + 05 = 705 (Hexa)

+ Operation Command = S(07Hex) + 06 = 706 (Hexa)

  • Set 706 (Hex) = 1 >>> Motor Run Forward
    = 2 >>> Motor Run Reverse
    = 0 >>> Motor Stop
Register Address for Monitoring

+ Output Frequency Address = M (08H) + 09 = 809 (Hex)

+ Input Power Address = 80A (Hex)

+ Output Current Address = 80B (Hex)

+ Output Voltage Address = 80C (Hex)

We need to set the same communication parameters as the inverter (8.1,Even).
Please install as shown below:

The software will automatically create the program as below:
