Hello, in previous posts I used many different types of PLC to control FUJI Frenic inverter, today I would like to continue to guide you to use Omron PLC to control it.
Specifically, I use the Omron CP1H PLC in combination with the CP1W-CIF12 Module at the expansion port number 2 of the PLC.
Connection Diagram CP1H & Fuji Frenic
Parameter Setting Fuji Frenic
In order for the inverter to run in Modbus-RS485 mode, we need to set the following parameters:
+ H30: 3 ( Control Motor via RS485 port)
+ Y01: 1 ( Salve No.1)
+ Y02: 0
+ Y03: 2
+ Y04: 2 (9600bps)
+ Y05: 0 (8bit)
+ Y06: 1 (Parity check: Even)
+ Y07: 1 (Stop bit = 1)
+ Y10: 0 (Modbus-RTU Selection)
+ Y99: 0
Modbus Address Table
Register for Control
>>> Frequency Reference = S (07H) + 05 = 705 (Hex)
>>> Operation Command = S (07H) + 06 = 706 (Hex)
- Set 705 (Hex) = 1 >>> Run Forward
- Set 705 (Hex) = 2 >>> Run Reverse
- Set 705 (Hex) = 0 >>> Stop
Register for Read Data Response
>>> Output Frequency = M (08H) + 09 = 809 (Hex)
>>> Output Voltage = M (08H) + 12 = 80C (Hex)
Omron CP1H Communication Configuration
Since the project uses CIF-CIF12 in port 2, we configure it as follows:
Controller Programming
+ Read/Write Distribution
+ Frequency Write Command
+ Motor Control Run
+ Read Data Response
+ Read Data Output
