ACS 800 drive prfibus communication status word change/edit?
Controlling through PLC profibus DP mode.
Question: I want to communicate Encoder Status for speed calculation (Parameter : 50.06 external/Internal) in any of the status word.
Which status word is suitable to transmit this and Which parameter needs to edit for this?
first of all you need to verify what type of ProfiBus PPO protocol you are using, you can verify what type of PPO you are using in parameter 51.04.
Then you can send from drive to PLC the actual speed of your drive - parameter 02.18 - using the first word free in group 51, for example 51.05 or 51.07 - but this depend on your programming words from drive to PLC that you are using. When you have finished the modify, do not forget to refresh the fieldbus with parameter 51.27
Make sure that in case of change, the PPO would be modify both in PLC and in drive, if you are not expert in ProfiBus I suggest you to use one expert technician.
Hope this help you
