AC Drives Function Block based on Profibus communication for Freelance
Can we use this function block ON THE associated app (AC Drives Function Block based on Profibus communication for Freelance ), to control third party drives from freelance (CBF)? If not then how do we accomplish it? need some suggestions on this.
no you must a have function for each brand, normally all AC Drives from
a vendor uses the same technic.
It´s actually, in theorie, rather simple.
The AC Drives uses one WORD for indicating status, Status WORD,
one för controlling, Control WORD.
The trick is to find how to mask this WORD, i.e what the different bit does.
Then you should have an analogue signal to the drive for controlling the speed,
At the end you need one or more analogue from the AC Drives to read Speed,
possibly Current, Tourqe and so on.
All this information you can get from your vendor of the AC Drive.
Pls let me know what type of AC Drive you plan to use,
maybe I have something in my "drawer"
