5.160.4 Function 4: |dnIn1| = |dnIn2|
Selection: C04085 = "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 = dnIn2
( 554)
5.160.5 Function 5: |dnIn1| > |dnIn2|
Selection: C04085 = "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 > dnIn2
( 555)
5.160.6 Function 6: |dnIn1| < |dnIn2|
Selection: C04085 = "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 < dnIn2
