-Additional tuning can be done with the PID parameters (''​KI'',​ ''​KP'',​ and ''​KD''​). ​ The ''​KA''​ setting is also helpful; it gives an extra boost on acceleration and extra brake on deceleration. ​ Changing these parameters can do badly so normally it is not recommended for users to adjust them, or if so to adjust them slowly starting with ''​KP''​.+Additional tuning ​of the servo loop giving analog feedback to the motors ​can be done with the PID parameters (''​KI'',​ ''​KP'',​ and ''​KD''​). ​ The ''​KA''​ setting is also helpful; it gives an extra boost on acceleration and extra brake on deceleration. ​ Changing these parameters can do badly so normally it is not recommended for users to adjust them, or if so to adjust them slowly starting with ''​KP''​.
  
 ASI has a test setup for tuning these parameters and we are happy to perform the tuning for particular applications if needed. ​ It is important to know the leadscrew pitch and move distance (the optimum amount of ''​KA''​ depends strongly on distance). ​ Usually sample mass is negligible. ​ Contact ASI for more details. ASI has a test setup for tuning these parameters and we are happy to perform the tuning for particular applications if needed. ​ It is important to know the leadscrew pitch and move distance (the optimum amount of ''​KA''​ depends strongly on distance). ​ Usually sample mass is negligible. ​ Contact ASI for more details.
