Function
You can calculate the result of the arithmetical function according to the formula:
dnOut_p +
dnIn_p
2 byDivision
·
Positive values in byDivision result in a division.
·
Negative values in byDivision result in a multiplication.
·
The output signal is limited to ±2 31 −1 encoder turns.
– The output signal cannot exceed this limit value.
