2.2.8 Comparison (L_CMP)

Function library LenzeDrive.lib

Analog signal processing

2−16

LenzeDrive.lib EN 1.7

2.2.8.4 Function 4: |nIn1_a| = |nIn2_a|

 Selection: byFunction = 4

 With this function, for instance, you can make the comparison "n

act

= 0".

 This function is the same as function 1. (^ 2−14)

– However, the absolute value of the input signals (without sign) is generated here before the

signal processing.

2.2.8.5 Function 5: |nIn1_a| > |nIn2_a|

 Selection: byFunction = 5

 With this function, for instance, you can make the comparison "n

act

| > |n

|" independently of

the direction of rotation.

 This function is the same as function 2. (^ 2−15)

– However, the absolute value of the input signals (without sign) is generated here before the

signal processing.

2.2.8.6 Function 6: |nIn1_a| < |nIn2_a|

 Selection: byFunction = 6

 With this function, you can make the comparison "n

act

| < |n

|" independently of the direction

of rotation.

 This function is the same as function 3. (^ 2−15)

– However, the absolute value of the input signals (without sign) is generated here before the

signal processing.
