What should you pay attention to with feedforward control on control block FB58 “TCONT_CP”?
Description: With control block FB58 “TCONT_CP” there might be incorrect behavior of the complete block if the “DISV” input is used. Using feedforward control should therefore always be avoided and the “DISV” input should be set permanently to “0”. Important: This is not normal behavior and only occurs under certain conditions. However, it results in the complete control block no longer working properly. Note: The behavior described above has been cleared in STEP 7 version V5.3 and higher.
