Fuji Frenic Modbus RTU Configuration

In order for the Fuji Frenic inverter to be controlled by Modbus RTU through the RS485 port, we need to set the following parameters:

+ H30: 3 (Run & Frequency Command via RS 485)

+ Y01: 1 (Slave Station No.)

+ Y02: 0

+ Y03: 2.0 ( Timer Error Detect)

+ Y04: 2 (9600bps)

+ Y05: 0 (8bit)

+ Y06: 1 (Even)

+ Y07: 1 (1bit)

+ Y10: 0 (Modbus-RTU)

+ Y99: 0 (Folow H30 Funtion)

Registers for Control

>>> Frequency Reference Address = S (07) + 05 = 705 (hex) = 1797 (dec)

>>> Motor Control Address = S (07) + 06 = 706 (hex) = 1798 (dec)

+ Set Word 1798 = 1 >>> Forward Run
= 2 >>> Reverse Run
= 0 >>> Stop

Registers for Monitoring

+ Output Frequency Address = M (08) + 09 = 809 (hex) = 2057 (dec)
