5.8. Controlled Head Motor CHM-1
The Controlled Head Motors CHM-1 are attached between the ARRIHEAD and the ARRIHEAD
hand wheels. They can be used on an ARRIHEAD-1, ARRIHEAD-2 or Encoded ARRIHEAD-2.
A hand wheel that is attached to a CHM-1 motor will turn an encoder. This encoder provides control
signals for a motor inside the CHM-1 that turns the ARRIHEAD drive shaft. There is no mechanical
connection between the hand wheel on the CHM-1 and the ARRIHEAD gears.
Using the CHM-1 on an ARRIHEAD feels very much like operating the ARRIHEAD without the
CHM-1, with one exception: it is not possible to stop a panning ARRIHEAD anymore by pushing on
the head or the camera. This takes a little getting used to. The head must be stopped with the Mimic
(usually the respective hand wheel) that is assigned to the CHM-1 motor.
The hand wheel on a CHM-1 motor does not necessarily have to control the CHM-1 motor. In fact, it
can be assigned to any motor attached to the ARRIMOTION system. It is, for instance possible to
assign the pan and tilt hand wheels of the CHM-1 to the pan and tilt functions of a snorkel lens.
