1Introduction
Dear Customer,
Thank you very much for buying a ATOM one - Motor Drive.
This manual gives you an overview of your new camera accessory.
The ATOM one - Motor Drive is the most precise solution to move analog
lenses remotely.
The ATOM one - Motor Drive works with almost all lenses that fit in the
mechanical dimensions.

2Technical Data
2.1 Dimensions
The Housing of the ATOM one - Motor Drive fits exact to the housing of the of
the ATOM oneand all ATOM one 4k mini models.
For simple mounting the motor has two 1/4” x 5mm tripod threads at the
bottom side.
Any custom specific mounting can be done with 2 additional M3x5mm mount
holes on bottom.
Please refer to the drawing below for details.

2.2 Power Consumption
The ATOM one - Motor Drive is powered through the camera. The power
Consumption depends on the actual load of the Motors. The maximal power
consumption is 2,9 W.
The maximum power consumption of motor drive and ATOM one 4k mini 16
is less than 12 W, so that it can be powered at 12V with less than 1A.
2.3 Precision
The resolution of the movement depends on the maximal turn angle of the
lens.
The ATOM one - Motor Drive probes the minimal und maximal boundaries of
the lens on every startup.

Max Range/ 100 (1% step)
Focus Movement
Max Range/ 1000 (0.1% step)
2.4 Required Tools for Assembly
For the assembly and the adjustment, the following tools are required:
1. 2mm hexagonal wrench
2. PH2 screwdriver

Lens preparation
7
3Lens preparation
The lenses must be equipped with special rubber gears.
3.1 Lens selection
Physical there are limitation to the minimum and maximum diameter with our
default gears.
3.1.1 Diameter limitation
If the lens is very small, the moveable gear of the motor drive cannot reach the
main gear. A custom gear can fix this limitation.
If the lens is to large it will block the motor. A custom plate can fix this
limitation.
Both working diameters can be found in the lens dimensions table.
3.1.2 Distance limitation
The motor position can be adjusted to reach the iris, focus or zoom position.
Depending of the used camera the minimum and maximum length is defined
in the lens dimensions table.
3.1.3 Lens Dimensions
The following dimensions are working with the default ATOM one - Motor
Drive kit.

3.1.4 Environmental Conditions
To prevent high lens torques (e.g. due to cold temperatures that harden the
grease inside the lens-mechanics) use only lenses according to their respective
temperature range (lens-spec).

3.2 Lens gear assembly
The ATOM one - Motor Drive comes with a set of special rubber gears.
The set includes 2 pieces of 25,30,35 and 40mm each. This gives a wide range
of lenses to be supported. These gears can expand by +5mm.
These gears are covering a diameter range of 27 to 45mm.
Select the next smaller gear depending of your given diameter.
It requires relative high force to push & slide the gear onto the lens.
Please refer to the following images for reference.

4Setting up the Motor Drive
Make sure that the lens is very tight, since the motor will create torque to it.
Use e.g. Teflon tape or Loctite to prevent the lens of loosening.
4.1 Mount the motor drive on the camera
First mount the connector plate on the bottom side of the camera with M3
PH2 screws.
Make sure, that the connector plate is mounted correctly:
Mount Point for Atom one
Mount Point for Atom one 4k mini
Back side View of the camera:
Connector plate

Setting up the Motor Drive
10
Slide the Motor from the back of the camera to the back over the connector
plate:
There are two M2 hex screws on the bottom of the ATOM one - Motor Drive .
The mount lock and motor adjust screw. Both are M2 hex.
Fix the motor on the connector plate by tighten the mount lock screw with
the 2mm hexagonal wrench.

Now adjust the gears to the lens.
Make sure, that the Motor adjust screw is loose.
The motor tubes can be pulled out of the housing, turned with a maximal angle
of 90°. Make sure, that the force pressing the motor gear in the lens gear is not
too high.
Align the motors to the gears of the lens. Tight the motor adjust screw.
Connect the Hirose connector in the AUX Port of the
camera.
During the boot process of the camera the motor
drive will be initialized. If everything works fine the
blue led should be blinking at the camera and at the
motor.

4.2 Optimize the motor parameters
It is recommended to optimize some motor parameters to get the best
movement of your lens for your needs.
4.2.1 Optimize the Torque Parameter
The torque parameter is used by the motor to find the boundaries of the lens
movement. If the Parameter is set to high, it is possible that the motor does
not stop at the end of the lens moving range and starts to turn the whole lens,
or the gears starts to overrun. On the other side if the parameter is set to low,
it is possible, that the motor stop to early during the initialization run.
In this case the full range of the lens can not be used.
The parameter is different for each lens. This optimization must be done by try
and error. A good start value is around 50.
The torque parameter can be set in the ProVideo Gui, in the lens drive tab. For
this purpose, the advanced lens setup must be enabled.
The stall detection is turned off after initializing. Make sure that the lens is not
blocked during a movement. In this case, the boundaries are shifted, and the
motor needs a new initialization.
4.2.2 Set the Iris F-Stop Table
For using the aperture positioning, the camera needs to know where exactly
the F-Stops are. The Table with this information can be set in the ProVideo GUI.

Setting up the Motor Drive
13
There are two possibilities to set the table.
1. Use the corresponding Lens Template.
2. If the used lens has no template, all F-Stops have to be filled in the
table by hand.
If all values are filled in correctly press ‘Transmit Table to Camera’ to store the
table in the camera.
For more Information refer to the ProVideo Gui Handbook.

5.1 RCP Remote Control
The ATOM one - Motor Drive is already integrated in the RCPs of CyanView,
Skaarhoj and in the Atom Wico Box to work with the Sony RCP1500.
5.2 ProVideo Control Software
The ATOM one - Motor Drive is fully integrated in the ProVideo camera control
software. It gives easy access to all the motor functions.
To use the software, you need a serial connection from ATOM camera to a
Windows PC. This can be done with a USB – RS485 adapter. You can build your
own adapter with a serial FTDI cable or purchase a cable from Dream Chip.
