Motor calibration
After connecting a lens motor to the camera and the lens axis, it must be
calibrated. Every time a lens motor has been deattached from the lens, it
must be recalibrated after reattachment. When CLM-2 or CLM-3 motors are
used, the camera will ask the user to calibrate the lens motors after booting
the camera. As a lens change or a change of the motor position during
power down would invalidate the calibration, the high motor torque of the
CLM-3 could damage the lens when driving with high force against the limit
of a lens axis. If the user is sure that no changes where made to the lens
and motor setup, he can skip this step.
Motor direction
The direction of the CLM-2 and CLM-3 motors can be changed in the
camera settings.
Motor torque
For CLM-3 motors, the motor torque can be adjusted in the camera settings.
Note: Make sure the motor torque level matches the current lens to avoid lens
damage.
3D lens sync
When two ALEXA Plus cameras are set Sensor sync EXT master and EXT
slave, the slave camera will switch off its radio module and receive motor
control commands from the master camera via the EXT connection.
Note: The matching of the master and slave cameras lens ring positions depends on
the mechanical accuracy and matching of the lenses. make sure the lenses in use
are matched as good as possible.
