5.161.4 Function 4: |dnIn1_n| = |dnIn2_n|
Selection: C04080 = "3"
• This function serves, for instance, to implement the comparison "n
act
= 0".
• This function behaves like function 1. However, the amount is generated by the input signals
before signal processing (without sign).
 Function 1: dnIn1_n = dnIn2_n ( 559)
5.161.5 Function 5: |dnIn1_n| > |dnIn2_n|
Selection: C04080 = "4"
• This function serves, for instance, to implement the comparison "|n
act
| > |n
x
|" independent of
the direction of rotation.
• This function behaves like function 2. However, the amount is generated by the input signals
before signal processing (without sign).
 Function 2: dnIn1_n > dnIn2_n ( 560)
5.161.6 Function 6: |dnIn1_n| < |dnIn2_n|
Selection: C04080 = "5"
• This function serves to implement the comparison "|n
act
| < |n
x
|" independent of the direction of
rotation.
• This function behaves like function 3. However, the amount is generated by the input signals
before signal processing (without sign).
 Function 3: dnIn1_n < dnIn2_n ( 561)
