The LS iG5A inverter has a powerful interface and is upgraded and optimized. iG5A provides open-loop vector control, PID control, and ground fault protection through powerful built-in functions. Along with that, it also supports Modbus RTU RS484 for convenient control

Today thelivingchristmascompany.com will guide you to use LabView software to control iG5A VFD. We need to prepare 1 USB to RS485 converter cable

LS iG5A Modbus RTU Configuration

In order for the inverter to be controlled by Modbus RTU, we need to set the parameters as shown below

thelivingchristmascompany.com recommends that you configure as below for the most stable communication speed

• Drv = 3
• Frq = 7
• I59 = 0
• I60 = 1
• I61 = 3
• I62 = 0
• I65 = 2

LS iG5A Registers Address List

Note: Control Address = “Register Address – 1”

• Motor Control Address = 6 – 1 = 5

+ Set Word 5 = 2 >>> Forward Run
= 4 >>> Reverse Run
= 0 >>> Motor Stop

• Frequency Reference Address = 5 -1 = 4

• Output Current Address = 9 – 1 = 8
