When the servo is first given a change in demand position, it will create a large drive signal to the motor and the damping term which backs off this signal will be small. As the demand position is neared, the damping signal gets larger to prevent overshoot.I know the software controls the servo, but how does the servo affect damping?

How do you think the firmware can affect damping?Initial impressions - the focus on my DA55-300 does seem faster, maybe slightly more damped, but it has made little difference to my DA*50-135.
Or in non geek speak, It will.

Fair play to you sir. Takes a big man to stand up and try to make a difference.

You are probably right Andy - the cells used in the K20 are 7.4V and capable of delivering a substantial burst of current.
