17.1.11.4 Function 4: |nIn1| = |nIn2|
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: nIn1 = nIn2
17.1.11.5 Function 5: |nIn1| > |nIn2|
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: nIn1 > nIn2
17.1.11.6 Function 6: |nIn1| < |nIn2|
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: nIn1 < nIn2
