Description
Rotator 281 is a rotator for stage use, mainly for use in theatres, shows and concerts.
It is designed for rotating lamps and other electrical devices. The rotator has a positioning
system that enables a Rotator to stop at any desired position. The load is up to 150 kg. The
rotation speed is between 0.15 rpm and 6.8 rpm.
The rotators are easily connected as a chain, allowing for advanced and creative ways of making
dynamic movements. The rotator is controlled by the DMX channels from the lighting desk. It
has a built-in positioning system which is utilized in locating the desired position. The positioning
system is controlled from a 16 bit DMX channel and is highly accurate; the rotator stops within
1
°
. The speed of the rotator is likewise controlled from the lighting desk, and it is possible to set
the left and right limits of the movement of the rotator, adjusting its span of motion. Six DMX
channels controls the wanted position and the speed of the movement, and the rotator finds the
position applied on the lighting desk. The movements are programmed as lighting and in
interaction with the light.
The control system ensures that the motor only is powered when:
The control signal is reliable.
The position and speed control is on.
The motor position is calculated after witch a PID regulator calculates the motor speed
and distance.
Rotator 281 should only be operated by an experienced DMX-controlled-lighting-desk-operator.
The lighting desk has to be programmed according to the manual, so the rotator will stop when
the speed is put to 0 %. It is also possible for the user to stop the rotator on the main. After
power failure the start and 0
°
position of the rotator needs to be reset before the rotator can
function again.
Manually operation of the rotator is only intended for mounting, service, and tests.
