New to PLC, using do-more PLC to control Lenze VFD

(1/1)

lukejenson:
Hi there,

I have a project that need to use automation direct do-more PLC to control a VFD which is Lenze ESV222N02TXB https://www.clrwtr.com/Products/ESV222N02TXB

I'm new to PLC and never done anything about modbus. But I watched the webinars and got the frame of the software.

Now, I still don't know how to connect the PLC with the VFD. I can program the PLC and make it the master, but I don't have a chance to program the VFD.

I saw that some people are using Mach3 to do something similar to what I'm trying to do.

So I'm here to see if anyone can tell me from the basic steps how to set up the connection between the PLC and VFD through modbus.

Appreciate for the help.

Regards

Explain what your goal is. I use Mach 3 and DoMore BRX which is a fabulous PLC. We talk Modbus to 7 VFDs at the same time. You can send me a private message if you like and I could send the code for Modbus from the PLC
