Hi Saisravan,

but I can't able write the commands. While writing commands to drive through Modbus communication in getting errors.

Which errors do you get?

Can anyone help me on this r else can any share code of yours!

Why should we share our code?

It's your code that gives errors, not ours: attach your code to get help to improve it!

What is this "ND r u" good for?

While writing commands to drive I'm getting errors. Just see the attachment. But I can able to read the values from drive. There is no issue. Only writing commands only problem. Actually my application is lift system.

Hi Saisravan,

apparently there is an error for Modbus function 6. Does your device support function code 6?

Hi Saisravan,

Need commands of ABB ACS880 drive

When you want to know the needed commands you need to read the manual of your device!

(I will not do this for you.)
