Accuracy & Electronic Backlash Comp
The MK3 motor features a high-precision encoder that will never lose steps. If
you see evidence of backlash affecting accuracy, please make sure that your
mount, rails and camera are extremely rigid, as mounting flex is the main
cause of inaccuracy. Unique electronic backlash compensation is calibrated at
the factory and will be tweak-able via future firmware update.
Focus/ Iris/ Zoom Assignment
The Digital Motor is internally assigned a “Motor Class”, which is saved to non-
volatile memory. The motor will identify itself to the CONTROLLER via its
SERIAL NUMBER (lasered onto the motor back, example: 0500). To change the
class of a Digital Motor, or other performance parameters (performance mode,
direction of rotation, etc.) please refer to the manual for the Controller.
