Checking the actual position value
After normalization of the encoder signal you should check the actual position value.
● You are online with the STARTER .
● You have selected the screen for "Actual value processing".
To ensure that the converter calculates the actual position value correctly, you must check
the following:
● There must be no overflow of the actual position value in the entire traverse range. The
converter can show as a maximum the value range of -2147483648 … 2147483647. If
this maximum value is exceeded, the converter reports fault F07493.
● If you have defined a modulo range, the converter resets the actual position value after
passing through the range.
You have now checked the calculation for the actual position value.
