DynaStick - Linear Slider / Rotary Motor Control System - Now in production

DynaStick  - Servo Motor Control System - Sale item

- Suitable for tracking systems, rotary systems, stage positioning etc

- Adjustable acceleration, deceleration & speed

- Intelligent user-settable soft stops (1-button entry)

- 4 x position memories

- Graphical position & speed displays

- RF, Timelapse, DMX options and more

This is a high performance brushless motor/encoder servo system - it is not stepper motors (although they too, and brushed DC motors, can be accurately controlled if required).

Suitable for both linear (slider) or rotary (roll-ring, turntable etc) systems - Enables exact end stops which can be set & cleared any time, fully variable speed using thumb control or external foot pedals etc (9 overall speed settings, with a pot as fine max speed setting), up to approx 30A drive current (depending on drive/motor choice). It has also been interfaced to mains-powered 1.5KW drives.

If you require updates, or the latest protocol (for PC control etc) relating to this product please use "Contact Us" (subject: DynaStick Update)

Price dependent on options/quantity. Please note that due to options, systems are built to final required specification. Please allow time for this when ordering.

Some uses so far:

ProSup Tango "TED" - The DynaStick is the current control system for the TED. Please contact us for price/availability of TED/Tango slider kits.
League of Legends - Used on the June/July 2022 series filmed in Singapore controlling 2 x TED Tango tracks, and 4 x under-desk mini tracks (DoP: Adam Levi Rodgers)

2018 FIFA World Cup Football BBC Russia (TV) - Used to control a ProSup Tango "TED" slider rail in the main BBC studio above Gary Lineker.

Life (Film) - This has been used for many weeks on "Life" controlling a roll ring, and slaved rolling monitor.
Scanning Turntable - An automated turntable /camera trigger system for product scanning (Clear Angle Studios Ltd) - "Accurate to 3 pixels" (24Mpix sensor)


GRAPHICAL POSITION DISPLAY: The display grapically  shows motor position (if end stops are both set),  joystick demand,  and motor speed  for clear user feedback.

DISPLAY / LEDS:  Ring LEDs display approximate motor speed, & direction of  motion. The main display can also show general parameters, and user settings.

SETTING END LIMITS: You can unplug the stick, & the drive will keep its limits - useful for changing batteries on the stick. The stick displays active end stops both on the display and with  LEDs.

TED - PROSUP TANGO ELECTRIC DRIVE: With compatible systems, eg  TED (Tango kit & TED both available from us) the system will ramp down at the ends of the track automatically, irrespective of length, without the need for user intervention or pre-calibration.

ACCELERATION / BRAKING: Both rates are separately adjustable on the stick.

SHOT-BOX POSITION MEMORY: There are 4 available "1-touch" motor position memories. The motor will drive to the selected position with  user-selectable ramp-up, ramp-down and speed settings. Positions are saved to memory for future recall*.

POSITION LOOP PLAYBACK: Position memories can be played back as a loop (0-9 or continuously) with the choice of memories (1-2, 1-3 or 1-4) and 2-59 seconds, or 1-60 minutes delay at each position (with software version BC+).
DRIVE UNIT:  The motor drive unit is extremely compact, measuring approx  82 x 69 x 36mm (3.2" x 2.7 "x 1.4"). A housed version is also available (approx 138 x 82 x 46mm)

HARDWARE OPTIONS: Currently the "standard" kit has a 10m RS-485 control cable - Options include RF link, batteries for the control stick (for RF use) etc, programer / drive battery backup  (to keep endstops, position etc for extended period - no longer req'd - autosaved in memory). *Shot memories are stored relative to track automatic end stops, which must be set before positions are automatically re-instated.

SOFTWARE OPTIONS (avalible on request):
The High Speed option will allow the drive to increase the maximum available motor speed proportionately to the battery / DC power input - It takes effect at around 22VDC, and will increase the maximum speed up to around 32VDC. On the TED system, this equates to a max speed of around 1.5m/s (standard speed is around 0.7m/s).
Settings are INTERVAL (2 seconds to 60 minutes) and NUMBER OF SHOTS (10-20,000). The drive will use position  memories 1 & 2 (^ & >) as start and end positions for the movement. Approx total time is displayed on the stick.
Control acceleration, deceleration, speed and 16-bit position through a DMX control desk (requires DynaStick DMX interface unit - available soon). If no user stops are set, the 16 bits utilise the whole track length (auto limits required), or between the user stops (if set).

Video - above left: Note change of arrows under "ES" as limits are set. 2nd top LED flashes when at limits. This video was before the position graph was implemented, but demonstrates the smoothness (direct motor shaft view)
Video - bottom left: Demonstrates how simple it is to set end limits. The numbers on the display are encoder counts (2000 per motor rev before the gearbox).
The "--" on the display is when no limits are set. <- shows 1 limit is set, <> means both limits set (<< or >> means limits reached, along with flashing limits LED) - When both limits are set, the graph changes to show position between limits.
