response mode is set to 2. The response time is

 

 

 

 

 

 

 

1000 ms when the velocity is greater than this

 

 

 

 

 

 

 

value, otherwise, it is 500 ms.

a.The number of samples used for smoothing depends on both the update_rate and resp_mode parameters. For instance, if the update_rate is 5 Hz and the resp_mode is 200ms, the number of samples used will be 10.
