Servomotor Lenses
This method is generally used in broadcast or videoconference-style lenses. The voltage range used for
servomotor style lenses is +2.5 to +7.5 VDC. These lenses can be controlled in two different modes:
positional mode
and
speed mode
.
Positional mode
is the most common servomotor mode. When voltage changes, the lens
moves and remains still until the voltage changes again. For example, if a lens receives a
voltage of +3 VDC, the lens moves to the corresponding position and stays there as long as the
voltage remains at +3 VDC. The movement speed of the lens motor is a function of the
PTE-300’s analog output. The lens servomotor receives the preset voltage when a preset is
recalled in the positional mode.
Speed mode
moves the lens when the voltage deviates from the center point of its range. The
farther the voltage moves away from the center point of reference, the faster the lens motor
moves. When the voltage returns to the center point, the lens stops wherever it is.
Pan and Tilt Control
Presets and travel limit stops are based on encoder counts from a
home
position index, located at the
center of each axis’s range of motion.
Zoom, Focus, and Iris Control
The PTE-300 utilizes the reference voltage limits from the lens (typically 2.5v to 7.5v) and drives the
zoom, focus, and iris axes within this range.
