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

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
