PLC with Powerflex VFD!
Hello I’m trying to control Powerflex 525 with a Delta AS series PLC, I’m using explicit messaging methode, I can read data from Powerflex for example nominal voltage etc, but I can not write or set new value to some parameters for example : ” Commanded Freq b002 ” and ” Drive Status b006 “. If anyone could help with this problem I would really appreciate it. Here are some photos of an example of the code!

Hi,
I don’t know about explicit messaging method but delta plc have some limitation sometimes. For example for modbus read / write they have some fix function while third party device not work on that function.
May be that was the issue with you..
Good Luck and share solution here if you find.
Thank You.
