Pan and Tilt
The Pan and Tilt parameters control the SHOWGUN fixture’s 420° pan range and 216° tilt range.
Pan and Tilt functions each utilize two channels to provide 16 bit adjustment to a fraction of a
degree.
Pan and Tilt motion for SHOWGUN fixtures can be controlled with MSpeed values, (see MSpeed
(Motor Speed) on page 34). If you choose to use MSpeed for gobo changes without affecting Pan
and Tilt parameters, set Pan/Tilt MSpeed OFF in the Control parameter.
Note: Optical encoders for pan and tilt correct the fixture’s position if the fixture is
jarred from its programmed position. If a physical obstruction prevents the
fixture from correcting its position, the fixture “times out” to prevent wear on the
motors. If your fixture has timed out, remove the obstruction and home the
fixture to return it to normal operation.
