camera lens.
Insert the ring to the lens and tighten the screw. Be sure the ring and the lens make good contact.
Mounting the Motor
The following steps show how to mount the motor to camera support rods. The motor comes with
rod clamp with two inner diameters.
1. Loosen the knob on the quick-release mount and attach the motor to the rod, and adjust the
quick-released mount on the motor so that the gear can make full contact with the lens.
2. Press the gear firmly against the lens and tighten the knob. Ensure the motor gear and the lens
ring make good contact.
3. Connect the power port on the motor to an external power supply by using the provided power
cable. For example, if you are using the camera mounted on the Ronin-M, connect the motor to
the P-TAP accessories power port on the Ronin-M.
If the data ports on the controller and motor is connected, the DJI Focus will work on
cable mode and the wireless mode is disable.
Make sure the motor is mounted securely.
Do not put your fingers near the motor when it is moving.
4. DJI Focus is able to work on cable mode and wireless mode. If you willing to use cable mode,
connect the data port on the controller to the other data port on the motor by using the signal
cable.

Calibrate
To control the lens accurately, you need to know the lens scale by calibrating the motor. The motor
must be calibrated once restart it.
Auto
It is recommended to calibrate the motor through the auto calibration if the lens has mechanical
limit. Auto calibration use the whole scale of the lens.
On the controller, select ‘Calibrate—>Auto’, the motor will control the lens to rotate until it reaches
the limit. When calibration is complete, select ‘Back’ to apply. You can suspend the calibration by
selecting ‘Stop’.
Manual
Manual calibration enables calibration of devices with no mechanical scale stops. To manually
calibrate:
