Hello everyone!
Continuing with the series of articles using MicroLogix 1100 PLC to control inverters via Modbus RTU RS485, today thelivingchristmascompany.com will guide you to connect to a Japanese inverter manufacturer Yaskawa.
And the model I use is Yaskawa V1000, this is the type of inverter commonly used in the world in all continents.

Yaskawa V1000 Modbus RTU Configuration
Below is a table of communication parameters for Yaskawa V1000 VFD
Register Control Address
Note: MicroLogix 1100 Address = “VFD Address (Dec) + 1“
>>> Control Address = 1 + 1 = 2
- Set Word 2 = 0000 0000 0000 0001 = 1 >>> Forward Run
= 0000 0000 0000 0010 = 2 >>> Reverse Run
= 0000 0000 0000 0000 = 0 >>> Stop
>>> Frequency Reference Address = 2 + 1 = 3
Register Monitoring Address
>>> Output Frequency Address = 24(hex) + 1 = 36 (dec) + 1 = 37
>>> Output Voltage Address = 25(hex) + 1 = 37 (dec) + 1 = 38
>>> Output Frequency Address = 26(hex) + 1 = 38 (dec) + 1 = 39
