Function

You can calculate the result of the arithmetical function according to the formula:

dnOut_p +

dnIn_p

byDivision

 Positive values in byDivision result in a division.

 Negative values in byDivision result in a multiplication.

 The output signal is limited to ±2

−1 encoder turns.

– The output signal cannot exceed this limit value.
