Hi there, Ronin-S Focus Motor is used with the Ronin-S Focus Wheel to control the focus, iris, and zoom.
As the Ronin-S's firmware only supports F (Focus) mode currently, when the Focus motor is turned on, if the mode is switched to I (Aperture) mode or Z (Zoom) mode, the LED will be solid red.
However, the gear ring can be mounted to the lens' focus ring to control the focus, and to the lens' zoom ring to control the zoom. The issue will be solved by a firmware update, thank you for your understanding and support.
