The AutofocusGainK parameter is a scale factor that is applied to the final position command from the autofocus loop. It is used with the AutofocusGainKi parameters to tune the autofocus loop. The autofocus controller consists of cascaded lag filters, which have the transfer function of the equation that follows.
For the most commonly used sensors (position or force), only AutofocusGainK, AutofocusGainKi1 Parameter, and AutofocusGainKi2 Parameter are needed.
To see the structure of the autofocus loop and guidance on tuning, refer to the Autofocus Functions topic.
