PLC Inovance “Modbus RTU” Yaskawa V1000 Tutorial

Written by

Hello everyone, continuing the Series using PLC Inovance H3U to control devices through Modbus-RTU RS485 communication, today continues to guide you to control Yaskawa V1000 inverters.

Yaskawa V1000 inverter is a universal inverter and also has a built-in RS485 port for convenient control by Modbus RTU.

Yaskawa V1000 “Modbus RTU” Parameters Settings

In addition to the basic parameters of the inverter installed according to the motor (voltage, current, frequency…) we need to install the following communication parameters:

Yaskawa V1000 “Modbus RTU” Parameters Address

+ VFD Control Address = 1

  • 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

>>> Output Frequency Address = 24 (Hexa)
>>> Output Voltage Address = 25 (Hexa)
>>> Output Frequency Address = 26 (Hexa)

PLC Inovance Modbus Configuration

You need to set up RS485 Port communication parameters. of the Inovance PLC is the same as the Yaskawa V1000 inverter
