Yaskawa V1000 series inverters feature compact design, high performance, quality and reliability. A new line of inverter technology that allows to control both asynchronous and synchronous motors. At the same time, the Yaskawa V1000 inverter also supports Modbus RTU (RS485) communication, which is convenient for controlling and monitoring the inverter.
In this project plc247.com uses PLC MicroLogix 1776-L32BXB in combination with Module 1763-NC01 to facilitate wiring (you can wire it directly through the Mini DIN-8Pin port of the PLC)

Yaskawa V1000 “Modbus-RTU” Parameters Setting
To be able to control Yaskawa V100 inverter with Modbus RTU, in addition to the basic parameters set by the motor (frequency, current, voltage), we need to install the following communication parameters
Yaskawa V1000 Registers for Control
Note: MicroLogix 1400 Address = “VFD Address (Dec) + 1“
>>> VFD 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
Yaskawa V1000 Registers for Monitoring
- 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
