

3.13.1 Overview

ForContinuousmode(“Continuous”)youselectthetotaldistancetherailwilltravel.Therail

willnotstopuntilitreachesitsfinalposition. Duringthistimetheshuttertriggerwillfire

continuously.Theshuttertriggerpulsetime(“Tpulse”)andtheofftime(“Toff”)ultimatelyset

thenumberofpicturesthatmaybetakenduringtherailmove.Thoseparametersareavailable

underthe“GlobalConfiguration”.Seesection3.3for moredetails.Because the numberof

picturesisdependentuponthetimeselected,apictureatthefinalpositionisnotguaranteed.

Alsokeepinmindthattherailacceleratesandde‐accelerates.Iftheramptimethatissetinthe

“GlobalConfiguration” screenislongitwillaffecttheamountofdistancetraveledbetween

pictures(thetimeisfixedbetweenpictures,notthedistance).



3.13.2 TotalDistance

Totaldistance(“Distance”)specifiesthecompletedistancetomovetherail.

Mode: Continuous

> Distance: 10.0 mm

Start (up/down)

Up=fwd / Down=back



3.13.3 StartingtheSequence

PresstheSELECTbuttonuntilitisnexttothe“Start(up/down)”text.

Mode: Continuous

Distance: 10.0 mm

> Start (up/down)

Up=fwd / Down=back



Thedirectionthattherailtravelsiscompletelydependentonwhichbuttonyoupresstoinitiate

thesequence.IfyoupresstheUPbutton,therailwillmovetowardthesubject.Ifyoupress

theDOWNbutton,itwillmoveaway.



Pressinganybuttonwillstopthemotorfrommovingtherailandabortthesequence.

3.14 AdvancedSettings

AdvancedsettingsareusedtocoupletheStackShotcontrollerwithanotherdeviceorrail.

ModifyingthesesettingsmaycauseStackShottonotfunctionproperlyandshouldnotbe

changedbythenoviceuser.ToenterStackShot’sAdvancedConfiguration,pressandholdthe

CONFIGbuttonforthreeseconds.Thedisplaywillchangeandlisttheavailableadvanced

settings.ToreturntothemainscreenpresstheCONFIGbutton.Thedifferentconfiguration

optionsarediscussedbelow.Allofthesesettingsaremaintainedwhenusingthe“Load/Save

Settings”optionandthroughpower‐cycles.TheSELECTbuttonwillmovetothenextavailable

configuration.ThedefaultsettingsmayberestoredbyholdingtheDOWNbuttonwhen

StackShotispoweredup.

3.14.2 Backlash

Thisparameterallowstheadjustmentofthebacklashcompensation.Whenthemotor

reversesdirectionthere(inmostapplications)willbesome“play”inthedrivemechanism.

StackShothasthecapabilitytocompensateforthisgearbacklash“play”.Backlash

compensationisappliedduring“AutomaticStep”mode,“AutomaticDistance”mode,and

anytimethat“AutoReturn”isenabled.UsetheUPandDOWNbuttonstoadjustthe

backlashforyourspecificapplication.Thedefaultisshownbelow.
