Hello soussia; It would be more efficient for you to read an explanatoion of how a scaling function works before we continue on this subject. I suggest you read the following FAQ, especially the quote extracted from it (an example of a pressure measurement): How and for which analog measurements can you use the function FC105 "SCALE" to convert the integer values (INT) into real number values?
So for your application set the low limit of your FC 105 at 0,0, and the high limit at 50.0. This way you are establishing your range in Hz (0 to 50) linked to your 0-20 mA signal. 0 mA/ decimal 0will show 0 (Hz) at the output of FC 105, 20 mA/ decimal 27648will show 50 (Hz), 10 mA/ decimal 13824will show 25 (Hz). You can then use the output address of the FC 105 to display on the HMI screen the Hz value of your drive. Hope this helps, Daniel Chartier |
