Changing the Prescaler Value of an Encoder 

For changing the prescaler value of an encoder, axis parameter 210 is used: 
  

-

 

To change the prescaler of encoder 0 use SAP 210, 0, <p>.  

-

 

To change the prescaler of encoder 1 use SAP 210, 1, <p>.  

-

 

To change the prescaler of encoder 2 use SAP 210, 2, <p>.

There are some special functions that can also be configured using these  values. To select these functions 
just add the following values to <p>: 
 

Add to <p> 

Special function 

16 

Null channel is active high (default: null channel is active low) 

8 

Hold encoder value only when null channel is triggered (default: always hold encoder value) 

4 

Clear encoder value when null channel is triggered (default: do not clear on null channel) 

2 

Trigger null channel at every N signal (default: only at next N signal) 

1 

Add when rotating CCW, subtract when rotating CW (default: add on CW, subtract on CCW) 

 

Example:  

For a prescaler value of 4 with an active high null channel use a p-value of 2048 + 16 = 2064
