Each motor can save data for up to 5 lenses. Before calibrating a lens, select the channel color to save the autofocus data for that lens. Double-click the motor button to cycle through 5 channels (red, yellow, green, blue, white). You can use labels to record which lens corresponds to each channel. After restarting the motor, simply set it to the corresponding color channel and perform automatic/manual lens calibration to extract the calibration data for that lens and enable autofocus mode. There is no need to recalibrate, and changing the device will not affect the saved data.
