17.1.28.4 Function 4: |dnIn1| = |dnIn2|
This function serves to implement e.g. the comparison "n
act
= 0". This function is similar to function
1. However, the amount is generated by the input signals before signal processing (without sign).
Function 1: dnIn1 = dnIn2
17.1.28.5 Function 5: |dnIn1| > |dnIn2|
This function serves to implement e.g. the comparison "|n
act
|>|n
x
|" irrespective of the direction of
rotation. This function is similar to function 2. However, the amount is generated by the input
signals before signal processing (without sign).
Function 2: dnIn1 > dnIn2
17.1.28.6 Function 6: |dnIn1| < |dnIn2|
This function serves to implement the comparison "|n
act
|<|n
x
|" independent of the direction of
rotation. This function is similar to function 3. However, the amount is generated by the input
signals before signal processing (without sign).
Function 3: dnIn1 < dnIn2
