Active focus control - newbie question

Hello, newbie question. Is active focus control possible with Voyager? If so, how does it work? Unfortunately, I couldn’t make sense of the description. A ZWO ASI6200mm (BIN2 on the Edge1100 HD) should be used in connection with a PrimaLuceLab ESATTO 4" focuser on the Takahashi FSQ-106EDX4 or a TCF-Leo 3-inch focuser on the Edge1100 HD with 0.7 reducer
